@microscopic-river-74022 Can I add files to a run action of type container?

Please stand by @salmon-scientist-57815 as I search the knowledge base. I normally take about 15 seconds or so. :wave:
---------------------- Yes, you can add files to a run action of type container in Garden. This is done using the
include
field in the action configuration. Here's how it works: The
include
field allows you to specify a list of POSIX-style paths or globs that should be regarded as source files for the action. These files will affect the computed version of the action. According to the container Run configuration reference (), you can use the
include
field like this:
Copy code
yaml
include:
  - my-app.js
  - some-assets/**/*
This example would include the
my-app.js
file and all files under the
some-assets
directory. It's important to note that for most Run actions, specifying
include
is usually not necessary as the relevant files are often implicitly inferred. However, it can be useful in certain scenarios, such as when you want to ensure a Run action is executed when specific files are modified. Additionally, you can also exclude files using the
exclude
field or by placing
.gardenignore
files in your source tree. These use the same format as
.gitignore
files. For more details on including and excluding files, you can refer to the Configuration Files guide ().

@microscopic-river-74022 would these files be added to the container and then be available to e.g. the command specified by the action>?

Let me check the knowledge base for you again. One moment! :books:
---------------------- To answer your question accurately, I need to clarify an important distinction regarding the
include
field in Garden's container Run actions. The
include
field for Run actions does not directly add files to the container or make them available to the command specified by the action. Instead, it serves a different purpose: 1. Version computation: The files specified in
include
are used to compute the version of the action. This affects when the action is considered to have changed and needs to be re-run. 2. Action context: These files define the context for the action, but they are not automatically added to the container or made available to the command. Reference: Run > container Run > Configuration Keys > include[] () If you want to make files available to the command inside the container, you typically need to: 1. Include the files in the Build action that creates the container image. 2. Use volumes to mount files or directories from the host into the container at runtime. The availability of files to the command depends on how the container image is built and how the Run action is configured, rather than the
include
field of the Run action itself. If you need to make specific files available to your command, you might want to look into configuring volumes for your Run action or ensuring the necessary files are included in the container image during the build process. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@microscopic-river-74022 that is what I thought. How can I create such a volume?
m
Let me check the knowledge base for you again. One moment! :books:
---------------------- To create a volume that can be used in a container Run action, you can use the
persistentvolumeclaim
action type in Garden. Here's how you can do it: 1. First, create a
persistentvolumeclaim
Deploy action:
Copy code
yaml
kind: Deploy
name: my-volume
type: persistentvolumeclaim
spec:
  spec:
    accessModes: [ReadWriteMany]
    resources:
      requests:
        storage: 1Gi
2. Then, in your container Run action, reference this volume:
Copy code
yaml
kind: Run
name: my-run
type: container
spec:
  volumes:
    - name: my-volume
      action: deploy.my-volume
      containerPath: /path/in/container
This configuration will create a PersistentVolumeClaim in your Kubernetes namespace and mount it at the specified
containerPath
in your container. A few important points to note: 1. The
accessModes
field is crucial. If you need to access the volume from multiple pods simultaneously, use
ReadWriteMany
. However, not all storage classes support this mode. 2. Ensure that your Run action has only one replica unless your volume supports
ReadWriteMany
. 3. The
action
field under
volumes
references the
persistentvolumeclaim
Deploy action you created. You can find more detailed information and examples in the following documentation: Kubernetes-plugins > Actions > Deploy > PersistentVolumeClaim () Reference > Action-types > Run > container Run > Configuration Keys > spec.volumes[] () Remember, this approach is specific to Kubernetes environments. If you're using a different provider, the method for creating and using volumes may vary. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@microscopic-river-74022 that sounds more complicated than necessary. What I need to do is construct a couple of files based on variables in the environment, get them into a container and call a script in there. Any other good options?
m
Let me check the knowledge base for you again. One moment! :books:
---------------------- You're right, and I apologize for suggesting a more complex solution than necessary. For your specific use case, there's a simpler and more direct approach using the
container
type Run action. Here's a better option that should meet your needs: 1. Use a
container
type Run action. 2. Utilize the
files
field to create files based on environment variables. 3. Specify the command to run your script. Here's an example of how you can configure this:
Copy code
yaml
kind: Run
type: container
name: my-run
spec:
  files:
    - path: /path/in/container/file1.txt
      content: ${var.content-for-file1}
    - path: /path/in/container/file2.txt
      content: ${var.content-for-file2}
  command: ["/bin/sh", "-c", "your-script.sh"]
In this configuration: 1. The
files
field allows you to specify files to be created in the container. The content can be templated using Garden variables, which can come from your environment or other sources. 2. The
command
field specifies the script to run inside the container. This approach lets you: - Construct files based on variables in the environment - Get these files into the container - Call a script that can use these files This method is more straightforward and doesn't require setting up persistent volumes or additional deploy actions. Reference: Run > container Run > Configuration Keys > spec.files[] () Remember to ensure that the base image for your container has the necessary tools and scripts (like
your-script.sh
in the example) to execute your desired operations. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

hmm, these files only exist for workflows.
