Build Service

Docker Remote Builder cannot push to private Cloudron Registry – no basic auth credentials due to read-only HOME / missing Docker config

Hello @miednr @miednr said in Docker Remote Builder cannot push to private Cloudron Registry – no basic auth credentials due to read-only HOME / missing Docker config: Could you please provide some commands to check, where the problem's cause is? I have set up my docker registery under dr.cloudron.dev and the build service under cbs.cloudron.dev. I run the command from the build service once: cloudron build login --url 'https://cbs.cloudron.dev' --build-token 4d9e63406e98c078e296f6f273d5d9adb080643d50dd1d82b687af8c414cf915 When I now build a custom app I run: cloudron build --file ./Dockerfile --set-repository dr.cloudron.dev/org.cloudron.copyparty --tag 0.1.0

Add better logging

docker build is building the image locally. cloudron build is pretty much doing the same thing but on a remote server. The code is at https://git.cloudron.io/packages/docker-builder-app/ . There is no difference other than what you already said.

cloudron build fais with error: Failed to upload app for building: 400 message: accessToken is missing

For those that are reading this post... If you plan to host the docker image yourself, this is critical to update the JSON of Docker Registry app with your Cloudron registry domain and credentials. @nebulon Maybe that would be a great idea to add to the documentation that if a user wants to host the image himself, he should use his Cloudron docker registry domain instead of docker.io. The documentation is currently confusing ^^ Thanks again for your assistance.

Build Service is maxing out CPU usage even though the app is only allowed 50% of resources

Ah yeah, that's what I thought. Moved the build app to somewhere else. Would be nice to add --cpu-quota to the build command to mirror the apps settings (from https://dev.to/code42cate/dont-build-docker-apps-without-this-flag-48kg)

Calling build inside a docker container

@girish works perfectly fine now, thanks for the quick fix

Updates?

@murgero yes, it should be safe to deploy within existing apps.

Set tag / pass docker args to remote build

stantropics — Tue, 18 May 2021 07:40:19 GMT

Just tried it and a cloudron build --set-build-service mybuild.service.com --build-service-token --set-repository / --tag latest now starts the build and pushes it to the repo. Thanks a thousand times, @girish. This is awesome.

Integrate a private docker registry

Right having unreliable and slow internet connection was one of the main reasons for us to create that buildservice app. For the repository URLs, this is more like a docker quirk. The build service just passes those strings forward to docker.
