CLI reference
=============
Most commands are run against one or more services. If the service is omitted, it will apply to all services.
Run `fig [COMMAND] --help` for full usage.
## build
Build or rebuild services.
Services are built once and then tagged as `project_service`, e.g. `figtest_db`. If you change a service's `Dockerfile` or the contents of its build directory, you can run `fig build` to rebuild it.
## help
Get help on a command.
## kill
Force stop service containers.
## logs
View output from services.
## ps
List containers.
## rm
Remove stopped service containers.
## run
Run a one-off command on a service.
For example:
$ fig run web python manage.py shell
By default, linked services will be started, unless they are already running.
One-off commands are started in new containers with the same config as a normal container for that service, so volumes, links, etc will all be created as expected. The only thing different to a normal container is the command will be overridden with the one specified and no ports will be created in case they collide.
Links are also created between one-off commands and the other containers for that service so you can do stuff like this:
$ fig run db psql -h db_1 -U postgres
If you do not want linked containers to be started when running the one-off command, specify the `--no-deps` flag:
$ fig run --no-deps web python manage.py shell
## scale
Set number of containers to run for a service.
Numbers are specified in the form `service=num` as arguments.
For example:
$ fig scale web=2 worker=3
## start
Start existing containers for a service.
## stop
Stop running containers without removing them. They can be started again with `fig start`.
## up
Build, (re)create, start and attach to containers for a service.
Linked services will be started, unless they are already running.
By default, `fig up` will aggregate the output of each container, and when it exits, all containers will be stopped. If you run `fig up -d`, it'll start the containers in the background and leave them running.
By default if there are existing containers for a service, `fig up` will stop and recreate them (preserving mounted volumes with [volumes-from]), so that changes in `fig.yml` are picked up. If you do no want containers to be stopped and recreated, use `fig up --no-recreate`. This will still start any stopped containers, if needed.
