Building my first addon

[mintyPT]

I'm trying to build a simple add-on just to test the waters. As such, I've been following a tutorial and reading the code for a couple of addons including the ones on the repo.

I managed to add an entry to the menu and create a react screen. Then I wanted to do a git clone inside the virtual machine but seems something does not work anymore.

I try to do it this way:

let site = this.props.sites[this.props.params.siteID]

let command = `"${context.environment.dockerPath}" exec ${site.container} git clone https://github.com/JeremyEnglert/JointsWP.git app/public/wp-content/themes/JointsWP`

childProcess.exec(command, { env: context.environment.dockerEnv }, cb);

The command executed is this one (for my case):

"/Applications/Local by Flywheel.app/Contents/Resources/extraResources/virtual-machine/vendor/docker/osx/docker" exec 496ce3fd7359ae48d9fa5c3ece296f2992d841ca5da401114f84c8e906839a58 git clone https://github.com/JeremyEnglert/JointsWP.git app/public/wp-content/themes/JointsWP

But sadly, I get the following response: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Any idea why? I tried the stats add-on and it's not working either. Might be the same issue.

Hi @mintyPT,

That might be happening because context.environment.dockerEnv isn't instantiated. I would recommend running console.log or similar on context.environment.dockerEnv to see if it has any contents. If it's not, you can have a function that fires setDockerEnv().

Also, instead of using childProcess.exec(), I would recommend using context.docker.docker. This is an instance of dockerode with a few helper methods.

Tip: Use const { docker } = context.docker; so you can simply run docker()

Here's an example using what you tried doing above

let site = this.props.sites[this.props.params.siteID]

docker().getContainer(site.container).execPromise(['git', 'clone', 'https://github.com/JeremyEnglert/JointsWP.git', 'app/public/wp-content/themes/JointsWP']).then(({ stdout }) => { 
    // Done
    console.log(stdout);
});
