Allow blocks prefixed with `x-` in the configuration as a place to declare reusable blocks with YAML anchors and aliases. Borrowed from the Docker Compose configuration file format - https://github.com/compose-spec/compose-spec/blob/main/spec.md#extension Thanks to @ruyrocha for the suggestion.

# Kamal Configuration
|
|
#
|
|
# Configuration is read from the `config/deploy.yml`
|
|
#
|
|
|
|
# Destinations
|
|
#
|
|
# When running commands, you can specify a destination with the `-d` flag,
|
|
# e.g. `kamal deploy -d staging`
|
|
#
|
|
# In this case the configuration will also be read from `config/deploy.staging.yml`
|
|
# and merged with the base configuration.
|
|
|
|
# Extensions
|
|
#
|
|
# Kamal will not accept unrecognized keys in the configuration file.
|
|
#
|
|
# However, you might want to declare a configuration block using YAML anchors
|
|
# and aliases to avoid repetition.
|
|
#
|
|
# You can use prefix a configuration section with `x-` to indicate that it is an
|
|
# extension. Kamal will ignore the extension and not raise an error.
|
|
|
|
# The service name
|
|
# This is a required value. It is used as the container name prefix.
|
|
service: myapp
|
|
|
|
# The Docker image name
|
|
#
|
|
# The image will be pushed to the configured registry.
|
|
image: my-image

# Asset Bridging
|

#
|

|
# If there are changes to CSS or JS files, we may get requests
|
|
# for the old versions on the new container and vice-versa.
|
|
#
|
|
# To avoid 404s we can specify an asset path.
|
|
# Kamal will replace that path in the container with a mapped
|
|
# volume containing both sets of files.
|
|
# This requires that file names change when the contents change
|
|
# (e.g. by including a hash of the contents in the name).
|
|
|
|
# To configure this, set the path to the assets:
|
|
asset_path: /path/to/assets
