Procedure
To add a service to the Docker PaaS, follow the following steps:
Docker container
- Prepare a Docker image if none is suitable
- Deploy dependencies services like databases
- When you need to interact from the command line with the container, prepare a wrapper script
- Configure the service in rOPS: pillar/paas/docker.sls
- Create a new service sls file in rOPS: roles/paas-docker/containers. The name must match the service name in the pillar.
nginx
If you need a nginx configuration, add it (again using service name) in rOPS: roles/paas-docker/nginx/files/vhosts.
If you don't need to configure anything, just add this in your file: {% include 'roles/paas-docker/nginx/files/vhosts/_default.conf' %}
To deploy your change, use one of the following:
salt equatower state_sls roles/paas-docker/nginx/configsalt equatower state.sls_id /etc/nginx/vhosts/phabricator/devcentral.conf roles/paas-docker/nginx/configif you need to pinpoint only your change
Replace equatower by the server to target.
Kernel
Kernel for the Docker Engine is configured through sysctl and tuned in rOPS: roles/paas-docker/kernel.
Cheat sheet
