Environment Variables

Environment contains are defined for each environment. They are to be stored using this directory structure config/docker/<service>/<environment>/.env.

Some variables are required at compile time. .env files defined at industrymoves/ will be overridden by those defined within nested directories.

.env SHOULD be kept out of source control, I am yet to decide upon the best approach to distributing them amongst the team.

Useful Docker commands

ANNIHILATE docker container stop $(docker container ls -a -q) 2> /dev/null; docker system prune -a -f

!!CAUTION!! the following command will clear persistent storage ie. local databases docker container stop $(docker container ls -a -q) 2> /dev/null; docker system prune -a -f --volumes

  • List all containers docker ps -a

  • Hook into STDOUT docker attach <container ID/name>

  • Get the IP address of a running postgres container instance

    docker inspect --format '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' postgres-${PG_MAJOR:-9.4}

  • Get the port of the running container instance (useful when docker run -P in which ports will be published randomly)

    docker port postgres-9.4 | grep -o "[0-9]*$"

  • Once built, you should save the compiled image docker save --output config/docker/db/postgres/$PG_MAJOR/postgres.tar. To load it again, run docker load --input config/docker/db/postgres/$PG_MAJOR/postgres.tar
