This module helps install OpenShift Origin
Platform As A Service. Through the declaration of the openshift_origin
class, you can configure the OpenShift Origin Broker, Node and support services
including ActiveMQ, MongoDB, named and OS settings including firewall,
services, and ntp.
The module can be installed directly via the puppet utility from PuppetForge:
puppet module install openshift/openshift_origin
Additionally, the module can be obtained from the github repository.
-
Download the Zip file from github
-
Upload the Zip file to your Puppet Master.
-
Unzip the file. This will create a new directory called puppet-openshift_origin-{commit hash}
-
Rename this directory to just
openshift_originand place it in your modulepath.
There is one class (openshift_origin) that needs to be declared on all nodes managing
any component of OpenShift Origin. These nodes are configured using the parameters of
this class.
class { 'openshift_origin' :
domain => 'example.com',
node_unmanaged_users => ['root'],
development_mode => true,
conf_node_external_eth_dev => 'eth0',
install_method => 'yum',
register_host_with_nameserver => true,
broker_auth_plugin => 'htpasswd',
broker_dns_plugin => 'avahi',
}
class { 'openshift_origin' :
domain => 'example.com',
node_unmanaged_users => ['root'],
development_mode => true,
conf_node_external_eth_dev => 'eth0',
install_method => 'yum',
register_host_with_nameserver => true,
broker_auth_plugin => 'remote-user',
broker_dns_plugin => 'nsupdate',
bind_krb_principal => $hostname,
bind_krb_keytab => '/etc/dns.keytab'
broker_krb_keytab => '/etc/http.keytab',
broker_krb_auth_realms => 'EXAMPLE.COM',
broker_krb_service_name => $hostname,
}
Please note:
-
The Broker needs to be enrolled in the KDC as a host,
host/node_fqdnas well as a service,HTTP/node_fqdn -
Keytab should be generated, is located on the Broker machine, and Apache should be able to access it (
chown apache <kerberos_keytab>) -
Like the example config below:
-
set
broker_auth_pluginto'kerberos' -
set
broker_krb_keytabandbind_krb_keytabto the absolute file location of the keytab -
set
broker_krb_auth_realmsto the kerberos realm that the Broker host is enrolled with -
set
broker_krb_service_nameto the FQDN of the enrolled kerberos service, e.g.$hostname
-
-
After setup, to test:
-
authentication:
kinit <user>thencurl -Ik --negotiate -u : <node_fqdn> -
GSS-TSIG (should return
nil):$ cd /var/www/openshift/broker $ bundle --local $ rails console $ d = OpenShift::DnsService.instance $ d.register_application "appname", "namespace", "node_fqdn" => nil
-
For any errors, on the Broker, check
/var/log/openshift/broker/httpd/error_log.
-
An exhaustive list of the parameters you can specify with puppet configuration follows.
|
Note
|
Passwords used to secure various services. You are advised to specify only alphanumeric values in this script as others may cause syntax errors depending on context. If non-alphanumeric values are required, update them separately after installation. |
Choose from the following roles to be configured on this node.
-
broker - Installs the broker and console.
-
node - Installs the node and cartridges.
-
msgserver - Installs ActiveMQ message broker.
-
datastore - Installs MongoDB (not sharded/replicated)
-
nameserver - Installs a BIND dns server configured with a TSIG key for updates.
-
load_balancer - Installs HAProxy and Keepalived for Broker API high-availability.
Default: ['broker','node','msgserver','datastore','nameserver']
|
Note
|
Multiple servers are required when using the load_balancer role. |
Choose from the following ways to provide packages:
-
none - install sources are already set up when the script executes (default)
-
yum - set up yum repos manually
-
repos_base
-
os_repo
-
os_updates_repo
-
jboss_repo_base
-
jenkins_repo_base
-
optional_repo
-
Default: yum
This flag is used to control some module behaviors when an outside utility (like oo-install) is managing the deployment of OpenShift across multiple hosts simultaneously. Some configuration tasks can"t be performed during a multi-host parallel installation and this boolean enables the user to indicate whether or not thos tasks should be attempted.
Default: false
Base path to repository for OpenShift Origin
Nightlies: https://mirror.openshift.com/pub/origin-server/nightly/rhel-6
Release (currently v4): https://mirror.openshift.com/pub/origin-server/release/4/rhel-6
Default: Nightlies
CPU Architecture to use for the definition OpenShift Origin yum repositories
Default: $::architecture fact
|
Note
|
Currently only the x86_64 architecture is supported.
|
Repository path override. Uses dependencies from repos_base but uses override_install_repo path for OpenShift RPMs. Used when doing local builds.
Default: none
The URL for a RHEL/Centos 6 yum repository used with the "yum" install method. Should end in x86_64/os/.
Default: no change
The URL for a RHEL/Centos 6 yum updates repository used with the "yum" install method. Should end in x86_64/.
Default: no change
The URL for a JBoss repositories used with the "yum" install method. Does not install repository if not specified.
The URL for a Jenkins repositories used with the "yum" install method. Does not install repository if not specified.
The URL for a EPEL or optional repositories used with the "yum" install method. Does not install repository if not specified.
Default: the root plus the domain, e.g. broker.example.com - except nameserver=ns1.example.com
These supply the FQDN of the hosts containing these components. Used for configuring the host’s name at install, and also for configuring the broker application to reach the services needed.
|
Note
|
if installing a nameserver, the script will create DNS entries for the hostnames of the other components being installed on this host as well. If you are using a nameserver set up separately, you are responsible for all necessary DNS entries. |
Default: undef
IP addresses of the first 3 MongoDB servers in a replica set. Add datastoreX_ip_addr parameters for larger clusters.
IP of a nameserver instance or current IP if installing on this node. This is used by every node to configure its primary name server.
Default: the current IP (at install)
When the nameserver is remote, use this to specify the key for updates. This is the "Key:" field from the .private key file generated by dnssec-keygen. This field is required on all nodes.
When the nameserver is remote, Kerberos keytab together with principal can be used instead of the dnssec key for updates.
When the nameserver is remote, this Kerberos principal together with Kerberos keytab can be used instead of the dnssec key for updates.
Example: 'DNS/[email protected]'
This and the next value are Amazon AWS security credentials. The aws_access_key_id is a string which identifies an access credential.
This is the secret portion of AWS Access Credentials indicated by the aws_access_key_id
This is the ID string for an AWS Hosted zone which will contain the OpenShift application records.
List of upstream DNS servers to use when installing a nameserver on this node.
Default: ['8.8.8.8']
This is used for the node to record its broker. Also is the default for the nameserver IP if none is given.
Default: the current IP (at install)
An array of broker hostnames that will be load-balanced for high-availability.
Default: undef
An array of Broker IP addresses within the load-balanced cluster.
Default: undef
The virtual IP address that will front-end the Broker cluster.
Default: undef
The hostame that represents the Broker API cluster. This name is associated to broker_virtual_ip_address and added to Named for DNS resolution.
Default: "broker.${domain}"
Sets the state of the load-balancer. Valid options are true or false. true sets the load-balancer as the active listener for the Broker cluster Virtual IP address. Only 1 load_balancer_master is allowed within a Broker cluster.

|
Note
|
The following resource limits must be the same with a given district. |
The max storage capacity allowed in each gear (1 block = 1024 bytes)
Default: 1048576
max_active_gears is used for limiting/guiding gear placement. For no over-commit, should be (Total System Memory - 1G) / memory_limit_in_bytes
Default: 100
no_overcommit_active enforces max_active_gears in a more stringent manner than normal, however it also adds overhead to gear creation, so should only be set to true when needed, like in the case of enforcing single tenancy on a node.
Default: false
gear max memory limit including swap (512M + 100M swap)
Default: 641728512
Enabling this configures NTP. It is important that the time be synchronized across hosts because MCollective messages have a TTL of 60 seconds and may be dropped if the clocks are too far out of synch. However, NTP is not necessary if the clock will be kept in synch by some other means.
Default: true
If configure_ntp is set to true (default), ntp_servers allows users to specify an array of NTP servers used for clock synchronization.
Default: ['time.apple.com iburst', 'pool.ntp.org iburst', 'clock.redhat.com iburst']
|
Note
|
Use iburst after every ntp server definition to speed up the initial synchronization. |
Set to true to cluster ActiveMQ for high-availability and scalability of OpenShift message queues.
Default: false
An array of ActiveMQ server hostnames. Required when parameter msgserver_cluster is set to true.
Default: undef
DEPRECATED: use msgserver_cluster_members instead, if both are set they must match
Default: $msgserver_cluster_members
Password used by ActiveMQ’s amquser. The amquser is used to authenticate ActiveMQ inter-cluster communication. Only used when msgserver_cluster is true.
Default "changeme"
This is the admin password for the ActiveMQ admin console, which is not needed by OpenShift but might be useful in troubleshooting.
Default: scrambled
This configures mcollective and activemq to use end-to-end encryption over TLS. Use enabled to support both TLS and non-TLS, or strict to only support TLS.
Default: 'disabled'

Default: mcollective/marionette
These are the username and password of the administrative user that will be created in the MongoDB datastore. These credentials are not used by in this script or by OpenShift, but an administrative user must be added to MongoDB in order for it to enforce authentication.
Default: admin/mongopass
|
Note
|
The administrative user will not be created if CONF_NO_DATASTORE_AUTH_FOR_LOCALHOST is enabled. |
These are the username and password of the normal user that will be created for the broker to connect to the MongoDB datastore. The broker application’s MongoDB plugin is also configured with these values.
Default: openshift/mongopass

Default: undef
An array of [host:port] of replica set hosts. Example: ['10.10.10.10:27017', '10.10.10.11:27017', '10.10.10.12:27017']
Default: undef
The file containing the $mongodb_key used to authenticate MongoDB replica set members.
Default: '/etc/mongodb.keyfile'
The key used by members of a MongoDB replica set to authenticate one another.
Default: 'changeme'
This user and password are entered in the /etc/openshift/htpasswd file as a demo/test user. You will likely want to remove it after installation (or just use a different auth method).
Default: demo/changeme
Salt and private keys used when generating secure authentication tokens for Application to Broker communication. Requests like scale up/down and jenkins builds use these authentication tokens. This value must be the same on all broker nodes.
Default: Self signed keys are generated. Will not work with multi-broker setup.
Customize default app templates for specified framework cartridges. Space-separated list of elements <cartridge-name>|<git url> - URLs must be available for all nodes. URL will be cloned as the git repository for the cartridge at app creation unless the user specifies their own. e.g.: DEFAULT_APP_TEMPLATES=php-5.3|http://example.com/php.git perl-5.10|file:///etc/openshift/cart.conf.d/templates/perl.git WARNING: do not include private credentials in any URL; they would be visible in every app’s cloned repository.
Default: ''
Enumerate the set of valid gear sizes for a given cartridge. If not specified, its assumed the cartridge can run on any defined gear size. Space-separated list of elements <cartridge-name>|<size1,size2> e.g.: VALID_GEAR_SIZES_FOR_CARTRIDGE="php-5.3|medium,large jbossews-2.0|large"

OpenShift Instance Name
Default: if ose_version == undef 'OpenShift Origin' if ose_version != undef 'Openshift Enterprise'
This setting is applied on a per-scalable-application basis. When set to true, OpenShift will allow multiple instances of the HAProxy gear for a given scalable app to be established on the same node. Otherwise, on a per-scalable-application basis, a maximum of one HAProxy gear can be created for every node in the deployment (this is the default behavior, which protects scalable apps from single points of failure at the Node level).
Default: false
Session secrets used to encode cookies used by console and broker. This value must be the same on all broker nodes.
Default: undef
Prefix/Suffix used for Highly Available application URL http://${HA_DNS_PREFIX}${APP_NAME}-${DOMAIN_NAME}${HA_DNS_SUFFIX}.${CLOUD_DOMAIN}

Default: true
When true, gear placement will fail if there are no available zones with the correct gear profile.
Default: false
desired minimum number of zones between which gears in application gear groups are distributed.
Default: 1
When true, enable access to the administration console. Authentication for the Administration Console is only handled via the ldap Broker Auth Plugin, using <code>broker_ldap_admin_console_uri</code>
Default: false
DNS plugin used by the broker to register application DNS entries. Options:
-
nsupdate - nsupdate based plugin. Supports TSIG and GSS-TSIG based authentication. Uses bind_key for TSIG and bind_krb_keytab, bind_krb_principal for GSS_TSIG auth.
-
avahi - sets up a MDNS based DNS resolution. Works only for all-in-one installations.
-
route53 - use AWS Route53 for dynamic DNS service. Requires AWS key ID and secret and a delegated zone ID
Default: 'nsupdate'
Authentication setup for users of the OpenShift service. Options:
-
mongo - Stores username and password in mongo.
-
kerberos - Kerberos based authentication. Uses broker_krb_service_name, broker_krb_auth_realms, broker_krb_keytab values.
-
htpasswd - Stores username/password in a htaccess file.
-
ldap - LDAP based authentication. Uses broker_ldap_uri.
Default: htpasswd
The KrbServiceName value for mod_auth_kerb configuration. This value will be prefixed with 'HTTP/' to create the krb5 service principal.
Default: hostname
The Krb5KeyTab value of mod_auth_kerb is not configurable — the keytab is expected in /var/www/openshift/broker/httpd/conf.d/http.keytab
URI to the LDAP server (e.g. ldap://ldap.example.com:389/ou=People,dc=my-domain,dc=com?uid?sub?(objectClass=*)). Set <code>broker_auth_plugin</code> to <code>ldap</code> to enable this feature.
LDAP DN (Distinguished name) of user to bind to the directory with. (e.g. cn=administrator,cn=Users,dc=domain,dc=com) Default is anonymous bind.
Password of bind user set in broker_ldap_bind_dn. Default is anonymous bind with a blank password.
URI to the LDAP server for admin console access (e.g. ldap://ldap.example.com:389/ou=People,dc=my-domain,dc=com?uid?sub?(objectClass=*)). Set <code>broker_external_access_admin_console</code> to enable this feature
kernel.shmmax sysctl setting for /etc/sysctl.conf
This setting should work for most deployments but if this is desired to be tuned higher, the general recommendations are as follows:
shmmax = shmall * PAGE_SIZE - PAGE_SIZE = getconf PAGE_SIZE - shmall = cat /proc/sys/kernel/shmall
shmmax is not recommended to be a value higher than 80% of total available RAM on the system (expressed in BYTES).
Default: kernel.shmmax = 68719476736
kernel.shmall sysctl setting for /etc/sysctl.conf, this defaults to 2097152 BYTES
This parameter sets the total amount of shared memory pages that can be used system wide. Hence, SHMALL should always be at least ceil(shmmax/PAGE_SIZE).
Default: kernel.shmall = 4294967296
Specify the container type to use on the node. * selinux - This is the default OpenShift Origin container type. At this time there are no other supported plugins.
Default: 'selinux'
Specify one or more plugins to use register HTTP and web-socket connections for applications. Options:
-
apache-mod-rewrite - Mod-Rewrite based plugin for HTTP and HTTPS requests. Well suited for installations with a lot of creates/deletes/scale actions. Deprecated in OSE 2.2.
-
apache-vhost - VHost based plugin for HTTP and HTTPS. Suited for installations with less app create/delete activity. Easier to customize. If apache-mod-rewrite is also selected, apache-vhost will be ignored
-
nodejs-websocket - Web-socket proxy listening on ports 8000/8444
-
haproxy-sni-proxy - TLS proxy using SNI routing on ports 2303 through 2308 requires /usr/sbin/haproxy15 (haproxy-1.5-dev19 or later).
Default: ['apache-vhost','nodejs-websocket']
List of user names who have UIDs in the range of OpenShift gears but must be excluded from OpenShift gear setups.
Default: []
External facing network device. Used for routing and traffic control setup.
Default: eth0
Public and private keys used for gears on the default domain. Both values must be defined or default self signed keys will be generated.
Default: Self signed keys are generated.
Number of seconds to wait before accepting another gear restart
Default: 300
Number of seconds a gear must remain inconsistent with it’s state before Watchman attempts to reset state
Default: 900
Wait at least this number of seconds since last check before checking gear state on the Node. Use this to reduce Watchman’s GearStatePlugin’s impact on the system.
Default: 0
Define a custom MOTD to be displayed to users who connect to their gears directly. If undef, uses the default MOTD included with the node package.
Default: undef
Setup DNS entries for this host in a locally installed bind DNS instance.
Default: false
The name of a zone to create which will contain OpenShift infrastructure. If this is unset then no infrastructure zone or other artifacts will be created.
Default: ""
A dnssec symmetric key which will grant update access to the infrastucture zone resource records.
This is ignored unless dns_infrastructure_zone is set.
Default: ""
When using a BIND key, use this algorithm for the infrastructure BIND key.
This is ignored unless dns_infrastructure_zone is set.
Default: 'HMAC-MD5'
An array of hashes containing hostname and IP Address pairs to populate the infrastructure zone.
This value is ignored unless dns_infrastructure_zone is set.
Hostnames can be simple names or fully qualified domain name (FQDN).
Simple names will be placed in the dns_infrastructure_zone. Matching FQDNs will be placed in the _dns_infrastructure_zone. Hostnames anchored with a dot (.) will be added verbatim.
Default: []
$dns_infrastructure_names = [
{hostname => "10.0.0.1", ipaddr => "broker1"},
{hostname => "10.0.0.2", ipaddr => "data1"},
{hostname => "10.0.0.3", ipaddr => "message1"},

Default: undef
Indicate whether or not this module will configure resolv.conf and network for you.
Default: true
Set this to the X.Y (ie: 2.2) version of Openshift Enterprise to ensure an Openshift Enterprise supported configuration is used.
See README_OSE.asciidoc distributed with the openshift_origin puppet module for more details.
Default: undef
Set this to true in order to allow Openshift Enterprise unsupported configurations. Only appropriate for proof of concept environments.
This parameter is only used when ose_version is set.
Default: false
This script attempts to automate as many tasks as it reasonably can. Unfortunately, it is constrained to setting up only a single host at a time. In an assumed multi-host setup, you will need to do the following after the script has completed.
-
Set up DNS entries for hosts.
If you installed BIND with the script, then any other components installed with the script on the same host received DNS entries. Other hosts must all be defined manually, including at least your node hosts. oo-register-dns may prove useful for this.
-
Copy public rsync key to enable moving gears.
The broker rsync public key needs to go on nodes, but there is no good way to script that generically. Nodes should not have password-less access to brokers to copy the .pub key, so this must be performed manually on each node host:
# scp root@broker:/etc/openshift/rsync_id_rsa.pub /root/.ssh/ (above step will ask for the root password of the broker machine) # cat /root/.ssh/rsync_id_rsa.pub >> /root/.ssh/authorized_keys # rm /root/.ssh/rsync_id_rsa.pub
If you skip this, each gear move will require typing root passwords for each of the node hosts involved.
-
Copy ssh host keys between the node hosts.
All node hosts should identify as the same host, so that when gears are moved between hosts, ssh and git don’t give developers spurious warnings about the host keys changing. So, copy /etc/ssh/ssh_* from one node host to all the rest (or, if using the same image for all hosts, just keep the keys from the image).
