Build errors with docker-compose.

[therealmaxmoon]

I am trying to install a local version of thredded to just test it, but I had no luck the last hours. Does someone have this forum software running so I could test it and just take a look, because installing it by myself looks like it costs a lot more time and energy.

I used the following command in the root directory of the repository:

docker-compose build

Used versions:

Docker version 20.10.5+dfsg1, build 55c4c88

docker-compose version 1.27.4, build unknown

The Errors:

I figured out that it must be executed as root and I didn't think about this, because in general I log in as root on my server to execute docker stuff.

So, if you're on a local machine and logged in as an unprivileged user, execute it as root:

sudo docker-compose build

But I ran into other errors:

Your Gemfile lists the gem capybara-screenshot (>= 0) more than once.
You should probably keep only one of them.
Remove any duplicate entries and specify the gem only once (per group).
While it's not a problem now, it could cause errors if you change the version of one of them later.

    rails (~> 7.0.0) was resolved to 7.0.7.2, which depends on

    thredded was resolved to 1.1.0, which depends on

How can this be solved?

Thank you for your help :)

Hi @therealmaxmoon

I've never used the Dockerfile in this repo, and it's quite old (hasn't been updated in the repo) and maybe the version of alpine is a bit old or there are other issues with the OOB ruby install (maybe bundler or rubygems needs updating or installing)? (I don't normally use alpine, so I'm a bit lost here) -- our CI doesn't use docker and I don't locally for testing either.

In terms of the sudo vs not sudo, i think that will depend on how you've installed docker and local issues (ie. it will vary from user to user)
