How to Create an App
To create your app, run the
create command. This 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
We currently support
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 CLI and run something like this
gigalixir create -n $APP_NAME
Once you deploy, you’ll be able to access your app from
How to Delete an App
To delete an app, run:
How to Rename an App
There is no way to rename an app, but you can delete it and then create a new one.
Make sure you migrate over your configs if you delete your app to rename it.
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 about sizing and scaling, see replica sizing.
gigalixir ps:scale --replicas=2 --size=0.6
When scaling an app down, please see What Happens when an App Scales Down - Graceful Shutdown.
We highly recommend running at least two replicas as soon as possible. This makes your application more resilient and can help share the load. See Adding More Replicas for benefits and considerations of adding more replicas. Users that solve the “how do I run multiple replicas” concerns early have better success at scaling their applications as they mature.
How to Check App Status
To see how many replicas are actually running in production (compared to how many are actually desired), run:
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
This will only show you your desired app configuration.
To see the actual status of your app, see App Status.
How to List Releases
Each time you deploy or rollback, a new release is generated.
To see all your previous releases, run:
How to View App Activity
We keep a record of each time you deploy, change configs, scale, etc.
To view the activity history, run:
How to Restart an App
For hot upgrades, See Hot Upgrades. We are working on adding custom health checks.
Restarts should be zero-downtime. See See How to Set Up Zero-Downtime Deploys.
