App Management¶
How to Create an App¶
To create your app, run the following command. It will also set up a git remote. This must be run from within a git repository folder. An app name will be generated for you, but you can also optionally supply an app name if you wish using gigalixir create -n $APP_NAME. There is currently no way to change your app name once it is created. If you like, you can also choose which cloud provider and region using the --cloud and --region options. We currently support gcp in v2018-us-central1 or europe-west1 and aws in us-east-1 or us-west-2. The default is v2018-us-central1 on gcp.

How to choose a name for your app¶
Normally, gigalixir generates a unique name for you automatically, but if you want, you can specify your app name. You’ll need to Install the Command-Line Interface and run something like this
gigalixir create -n $APP_NAME
That should do it. Once you deploy, you’ll be able to access your app from https://$APP_NAME.gigalixirapp.com.
How to Rename an App¶
There is no way to rename an app, but you can delete it and then create a new one. Remember to migrate over your configs.
How to Scale an App¶
You can scale your app by adding more memory and cpu to each container, also called a replica. You can also scale by adding more replicas. Both are handled by the following command. For more information, see Replica Sizing.
gigalixir ps:scale --replicas=2 --size=0.6
How to Check App Status¶
To see how many replicas are actually running in production compared to how many are desired, run
gigalixir ps
How do I manage multiple apps?¶
All relevant CLI commands can take an optional --app_name flag to specify which app you want to run the command on. Or, if you prefer, you can use the GIGALIXIR_APP environment variable instead. Without the app name, Gigalixir tries to auto-detect the app name based on your git remotes which works fine when you only have one app.
How to List Apps¶
To see what apps you own and information about them, run the following command. This will only show you your desired app configuration. To see the actual status of your app, see How to Check App Status.
gigalixir apps
How to List Releases¶
Each time you deploy or rollback a new release is generated. To see all your previous releases, run
gigalixir releases
How to View App Activity¶
We keep a record of each time you deploy, change configs, scale, etc. To view the activity history, run
gigalixir apps:activity
How to Restart an App¶
gigalixir ps:restart
For hot upgrades, See Hot Upgrades. We are working on adding custom health checks.
Restarts should be zero-downtime. See How to Set Up Zero-Downtime Deploys.
