Problem with Project with build section

[Jorman]

Hi, I created a project and is working, but when I add a build section I get some errors. I'm new to docker and maybe is a stupid question. The docker file, built outside Yacht is working but when I Up the Project I've problems. This's the Project with build section:

version: '3'

But, if I Up the Project I get this error

`Bad Request: build path /yacht/AppData/Config/qBittorrent/Scripts either does not exist, is not accessible, or is not a valid URL.`
So, seems that there's some error with permission of file, so, I copied the Docker file and the script inside Yacht directory, where also is the docker-compose file, here `/var/lib/docker/volumes/yacht/_data/compose/qBittorrent_Pia-Wireguard_Port-Forward` and I modified the build section like this `build: .` to build the Dockerfile that's in the same folder of docker-compose file but also this time the build make error:

This's a bug or I do some errors?

The build should be relative to the path of the project file. So in /config/compose/$projectname is where you'll want to add your stuff and you can use the relative path from there (make sure you're referencing from inside of the container's filesystem and not the host's filesystem.

[Jorman]

The sh script use localhost address, maybe I've to change this, I don't know yet, I'm under test, but the Dockerfile point to /Scripts that is mounted inside container (I think is right this) Ok, I forgot that also Yacht is a container with volumes, so, I copied the Docker file and .sh file inside /var/lib/docker/volumes/yacht/_data/compose/qBittorrent_Pia-Wireguard_Port-Forward is correct? But I always have this error: Bad Request: The projectname variable is not set. Defaulting to a blank string. Building with native build.

Sorry bad nob error, I updated the build string with $projectname, but $projectname is not set, I don't know how to set it up, but I can manually set the projectname, but always error: Bad Request: Building with native build.

[skluthe]

$projectname in that example is just a placeholder for the folder that your project is in.

[Jorman]

Yes you right, reading the error log I see that. I update the docker-file, see last comment, I always get error

[SelfhostedPro]

@Jorman FileNotFoundError: [Errno 2] No such file or directory: 'docker' It looks like the docker directory doesn't exist within the project.

[spacedentist]

I found that running apk add docker-cli inside the Yacht container fixes this problem.

The error message says No such file or directory: 'docker', and I think it means that the docker executable is missing. I suspect docker-compose executes the docker command line tool (probably calls "docker build"). And the Yacht image doesn't come with it installed.

[skluthe]

I’ll go ahead and add that into the image later today. Thanks for the heads up!

[Jorman]

Thank you all for the information
