Set tag / pass docker args to remote build

[stantropics]

Hi everyone,
I am trying to build remotely using the build services which works perfectly. However, docker build generates a tag by itself. How can I make it use a predefined tag?

Any help is apreciated.
Thanks a lot in advance.

@stantropics Can you clarify what you mean by docker build generates a tag by itself? Do you mean the latest tag? You can tag the image however you want using docker build -t image:tag no?

Also, you ask about passing args. You can pass args like cloudron build --build-arg MAXMIND_LICENSE_KEY=somekey for example. This is the same as docker build --build-arg but works with the build service.

@girish I have totally failed in describing my issue, sorry.
I am not talking about docker buildbut about cloudron build. It works perfectly when you follow the documentation. However, I am currently working on setting up a drone CI pipeline for a custom app. While doing this I have two issues:

1. One cannot pass the build-service url when using --set-build-service(like --set-build-service mybuild.service.com) It is not simple to answer the promt in the CI
2. I cannot find a way to set a fixed tag like "latest" or "0.1.0". As you can see in the documentation cloudron build sets "20191113-015207-340e7f520" as the tag automatically.

Hope it becomes clearer now.
Unfortunately I was not able to solve this by myself yet - so if someone has a hint for me I would be happy.

@stantropics ah, understood now! I released a new CLI version that should solve both your issues. npm install -g cloudron@4.12.0 .

• You can then pass --set-build-service mybuild.service.com . A token is also needed for authentication. So --build-service-token <token> . Currently, there is no UI to get this token, but it's in the /app/data/tokendb.json file of the build service.
• You can now pass --tag 0.1.0 (important: only the tag without the repo name. repo name is set with --set-repository as before)

Just tried it and a cloudron build --set-build-service mybuild.service.com --build-service-token <token-from-/app/data/tokendb.json> --set-repository <your.docker.registry>/<appname> --tag latest now starts the build and pushes it to the repo. Thanks a thousand times, @girish. This is awesome.
