Is there an easy way to include update modules in my yocto-based image?

For state scripts there’s the mender-state-scripts class one can inherit from. I’m hoping something similar exists.

Thanks for the help and the great product!

Hi @mterwoord,

You mean just installing the Update Modules on the client? Or would you like to generate Update Module Artifacts during a Yocto build as well?

You can make sure the Update Modules are installed by providing the following packageconfig as is done in meta-mender-demo,

[https://github.com/mendersoftware/meta-mender/blob/master/meta-mender-demo/recipes-mender/mender/mender\_%.bbappend#L9](https://github.com/mendersoftware/meta-mender/blob/master/meta-mender-demo/recipes-mender/mender/mender_%25.bbappend#L9)

We do not have any classes to generate the actual Update Module artifacts, this is very depended on what Update Module you are using and hard to create generic solutions.

I have started on writing something for the [dir-overlay](https://hub.mender.io/t/directory-overlay/529) module, this can work as inspiration.

Yes, I mean installing the modules on the client.

I can’t find how to get a module installed.

This is how, this will install all the modules that are available in the [mender client source](https://github.com/mendersoftware/mender/tree/master/support/modules)

I will result in calling this,

Cool. I searched around using github search, but install-modules didn’t show up there.  
How can I add extra modules? I have a variant of the directory module, which stops/starts a systemd service.

You could create a custom recipe, and make sure to install it to `/usr/share//mender/modules/v3/`, or add it to the `mender_%.bbappend`
