var appNewDescription = `Creates a new app from a default recipe.
|
|
|
|
This new app configuration is stored in your $ABRA_DIR directory under the
|
|
appropriate server.
|
|
|
|
This command does not deploy your app for you. You will need to run "abra app
|
|
deploy <app>" to do so.
|
|
|
|
You can see what recipes are available (i.e. values for the [recipe] argument)
|
|
by running "abra recipe ls".
|
|
|
|
Recipe commit hashes are supported values for "[version]".
|
|
|
|
Passing the "--secrets/-S" flag will automatically generate secrets for your
|
|
app and store them encrypted at rest on the chosen target server. These
|
|
generated secrets are only visible at generation time, so please take care to
|
|
store them somewhere safe.
|
|
|
|
You can use the "--pass/-P" to store these generated passwords locally in a
|
|
pass store (see passwordstore.org for more). The pass command must be available
|
|
on your $PATH.`
