Initial Harbor tasks

YouTube video: https://youtu.be/DcArQEFgk5s

Let's do some initial Harbor configuration on second Harbor instance: https://harbor.mylabs.dev

If you are using Let's Encrypt "staging" you need to download and use their "Fake LE Root X1" certificate for curl, helm and k8s cluster:

test -d tmp || mkdir tmp
cd tmp
if [ ${LETSENCRYPT_ENVIRONMENT} = "staging" ]; then
  sudo mkdir -pv /etc/docker/certs.d/harbor.${MY_DOMAIN}/
  CA_CERT=$(kubectl get secrets ingress-cert-staging -n cert-manager -o jsonpath="{.data.ca\.crt}")
  [ "${CA_CERT}" != "<nil>" ] && echo ${CA_CERT} | base64 -d > ca.crt
  test -s ca.crt || wget -q https://letsencrypt.org/certs/fakelerootx1.pem -O ca.crt
  sudo cp ca.crt /etc/docker/certs.d/harbor.${MY_DOMAIN}/ca.crt
  export SSL_CERT_FILE=$PWD/ca.crt
  for EXTERNAL_IP in $(kubectl get nodes --output=jsonpath="{.items[*].status.addresses[?(@.type==\"ExternalIP\")].address}"); do
    ssh -q -o StrictHostKeyChecking=no -l ec2-user ${EXTERNAL_IP} \
      "sudo mkdir -p /etc/docker/certs.d/harbor.${MY_DOMAIN}/ && sudo wget -q https://letsencrypt.org/certs/fakelerootx1.pem -O /etc/docker/certs.d/harbor.${MY_DOMAIN}/ca.crt"
  done
  echo "*** Done"
fi

Output:

LDAP Authentication

List users which are in Active Directory:

ldapsearch -LLL -x -h winad01.${MY_DOMAIN} -D cn=ansible,cn=Users,dc=mylabs,dc=dev -w ansible_secret_password -b cn=users,dc=mylabs,dc=dev -s sub "(cn=aduser*)" dn name description memberOf

Output:

List groups which are in Active Directory:

Configure LDAP/Active Directory authentication in Harbor by going to Administration -> Configuration -> Authentication:

  • Auth Mode: LDAP
  • LDAP URL: ldap://winad01.mylabs.dev
  • LDAP Search DN: cn=ansible,cn=Users,dc=mylabs,dc=dev
  • LDAP Search Password: ansible_secret_password
  • LDAP Base DN: cn=users,dc=mylabs,dc=dev
  • LDAP UID: sAMAccountName
  • LDAP Scope: OneLevel
  • LDAP Group Base DN: cn=users,dc=mylabs,dc=dev
  • LDAP Group GID: sAMAccountName
  • LDAP Group Admin DN: cn=adgroup03,cn=users,dc=mylabs,dc=dev
  • LDAP Group Scope: OneLevel

It's possible to use API call as well:

curl -u "admin:admin" -X PUT "https://harbor.${MY_DOMAIN}/api/configurations" -H "Content-Type: application/json" -d \
"{
  \"auth_mode\": \"ldap_auth\",
  \"ldap_base_dn\": \"cn=users,dc=mylabs,dc=dev\",
  \"ldap_filter\": \"(objectClass=organizationalPerson)\",
  \"ldap_group_admin_dn\": \"cn=adgroup03,cn=users,dc=mylabs,dc=dev\",
  \"ldap_group_attribute_name\": \"sAMAccountName\",
  \"ldap_group_base_dn\": \"cn=users,dc=mylabs,dc=dev\",
  \"ldap_group_search_filter\": \"(objectClass=group)\",
  \"ldap_group_search_scope\": 1,
  \"ldap_scope\": 1,
  \"ldap_search_dn\": \"cn=ansible,cn=Users,dc=mylabs,dc=dev\",
  \"ldap_search_password\": \"ansible_secret_password\",
  \"ldap_uid\": \"sAMAccountName\",
  \"ldap_url\": \"ldap://winad01.${MY_DOMAIN}\",
  \"token_expiration\": 300
}"

Harbor Authentication Configuration page

Open a new tab with Harbor login page (https://harbor.mylabs.dev) and login as:

  • User: aduser01
  • Password: admin

You should see limited view on the right side containing only Projects and Logs:

Open a new tab with Harbor login page (https://harbor.mylabs.dev) and login as:

  • User: aduser06 and aduser05
