Running GeoServer Cloud

This documentation describes how to run GeoServer Cloud with podman withouth pods (traditional way) based on

Creating network

podman network create gs-cloud-network

Creating volumes

Persistent storage for Rabbitmq

podman volume create rabbitmq_data

Creating a shared directory for the different GeoServer containers, e.g. webui, wms, etc.

podman volume create shared_data_directory

Downloading images

In order to speed up the "starting" part of the documentation we are going to download the images as the first stop

podman pull docker.io/library/rabbitmq:3.9-management 
export GSCLOUD_VERSION=1.3.0

for service in discovery config gateway admin-server rest webui wms wfs wcs
do
  podman pull docker.io/geoservercloud/geoserver-cloud-$service:${GSCLOUD_VERSION}
done

Creating primary containers

Following containers are required as the "base system".

Please start the containers in the described order:

Rabbitmq

podman run -d --name=rabbitmq --network gs-cloud-network -v rabbitmq_data:/var/lib/rabbitmq --restart always rabbitmq:3.9-management

Discovery

podman run -d --name=discovery --hostname=discovery \
  --network gs-cloud-network \
  -p 8761:8761 \
  --restart always \
  geoservercloud/geoserver-cloud-discovery:$GSCLOUD_VERSION

Accepted environment variables default values:

-e SERVER_PORT=8761
-e EUREKA_INSTANCE_HOSTNAME=discovery

Config

podman run -d --name=config --hostname=config \
  --network gs-cloud-network \
  -e SPRING_PROFILES_ACTIVE=git \
  -e CONFIG_GIT_URI=https://github.com/geoserver/geoserver-cloud-config.git \
  -e SPRING_CLOUD_CONFIG_SERVER_GIT_DEFAULT_LABEL=v1.3.0 \
  -e CONFIG_GIT_BASEDIR=/opt/app/git_config \
  geoservercloud/geoserver-cloud-config:$GSCLOUD_VERSION

Accepted environment variables default values:

-e EUREKA_SERVER_URL=http://discovery:8761/eureka
-e SPRING_PROFILES_ACTIVE=git
-e CONFIG_GIT_URI=https://github.com/geoserver/geoserver-cloud-config.git
-e SPRING_CLOUD_CONFIG_SERVER_GIT_DEFAULT_LABEL=master
-e CONFIG_GIT_BASEDIR=/opt/app/git_config
-e CONFIG_NATIVE_PATH=/opt/app/config

Gateway

podman run -d --name=gateway \
  --network gs-cloud-network \
  -p 9090:8080 \
  geoservercloud/geoserver-cloud-gateway:$GSCLOUD_VERSION

Accepted environment variables default values:

-e EUREKA_SERVER_URL=http://discovery:8761/eureka

Admin server

podman run -d --name=admin-server \
  --network gs-cloud-network \
  -p 9091:8080 \
  --restart always \
  geoservercloud/geoserver-cloud-admin-server:$GSCLOUD_VERSION

Creating service containers

Depending on your use case you can start any of the following containers.

Accepted environment variables default values:

-e EUREKA_SERVER_URL=http://discovery:8761/eureka
-e SPRING_PROFILES_ACTIVE=datadir|jdbcconfig
-e GEOSERVER_DATA_DIR=/opt/app/data_directory

for service in webui rest wms wfs wcs
do
  podman run -d --name=rest \
    --network gs-cloud-network \
    -e SPRING_PROFILES_ACTIVE=datadir \
    -v shared_data_directory:/opt/app/data_directory \
    geoservercloud/geoserver-cloud-rest:$GSCLOUD_VERSION
done

Integration with systemd

For better integration with your linux distribution which has to be based on systemd. Of course, the containers will be running for security reasons with a normal user account.

Preparing systemd

mkdir -p ~/.config/systemd/user/

Creating "base system" systemd files

for service in rabbitmq discovery config gateway admin-server
do
  podman generate systemd --new -n $service > ~/.config/systemd/user/container-$service.service
done
Removing running containers
podman rm -f rabbitmq discovery config gateway admin-server

Adjusting dependencies base system

for service in config gateway admin-server
do
  sed -i "/Wants=network-online.target/c\Wants=network-online.target container-discovery.service" ~/.config/systemd/user/container-$service.service
  sed -i "/After=network-online.target/c\After=network-online.target container-discovery.service" ~/.config/systemd/user/container-$service.service
done
Enabling and starting containers with systemd
systemctl --user enable --now container-rabbitmq container-discovery container-config container-gateway container-admin-server

Creating "service containers" systemd files

for service in rest webui wms wfs wcs
do
  podman generate systemd --new -n $service > ~/.config/systemd/user/container-$service.service
  podman rm -f $service
  sed -i "/Wants=network-online.target/c\Wants=network-online.target container-config.service" ~/.config/systemd/user/container-$service.service
  sed -i "/After=network-online.target/c\After=network-online.target container-config.service" ~/.config/systemd/user/container-$service.service
  systemctl --user enable --now container-rest
done
