SubType string

Dynamic YES

The list of tag of this image.

If pushing to a custom registry, the tag should include the registry URL. Note that if you want to push to an insecure registry (HTTP), you need to edit the /etc/docker/daemon.json file on your Kestra host to this and restart docker service (sudo systemctl daemon-reload && sudo systemctl restart docker).

SubType string

Dynamic YES

Optional build arguments in a key: value format.

Dynamic YES

Docker configuration file.

Docker configuration file that can set access credentials to private container registries. Usually located in ~/.docker/config.json.

Dynamic YES

The contents of your Dockerfile passed as a string, or a path to the Dockerfile

Dynamic YES

The URI of your Docker host e.g. localhost

Dynamic YES

The files to create on the local filesystem. It can be a map or a JSON object.

SubType string

Dynamic YES

Additional metadata for the image in a key: value format.

Dynamic NO

Inject namespace files.

Inject namespace files to this task. When enabled, it will, by default, load all namespace files into the working directory. However, you can use the include or exclude properties to limit which namespace files will be injected.

SubType string

Dynamic YES

The target platform for the image e.g. linux/amd64.

Dynamic YES

Default true

Always attempt to pull the latest version of the base image.

Dynamic YES

Default false

Whether to push the image to a remote container registry.

The generated image id.

Dynamic YES

Default true

Whether to enable namespace files to be loaded into the working directory. If explicitly set to true in a task, it will load all Namespace Files into the task's working directory. Note that this property is by default set to true so that you can specify only the include and exclude properties to filter the files to load without having to explicitly set enabled to true.

SubType string

Dynamic YES

A list of filters to exclude matching glob patterns. This allows you to exclude a subset of the Namespace Files from being downloaded at runtime. You can combine this property together with include to only inject a subset of files that you need into the task's working directory.

Dynamic YES

Default OVERWRITE

Possible Values

OVERWRITEFAILWARNIGNORE

Comportment of the task if a file already exist in the working directory.

SubType string

Dynamic YES

A list of filters to include only matching glob patterns. This allows you to only load a subset of the Namespace Files into the working directory.

SubType string

Dynamic YES

Default ["{{flow.namespace}}"]

A list of namespaces in which searching files. The files are loaded in the namespace order, and only the latest version of a file is kept. Meaning if a file is present in the first and second namespace, only the file present on the second namespace will be loaded.
