Unable to create repository inside Camel K container

Question

I have camel-k installed in a kubernetes cluster and in that there is a route to checkout a git repository as follow.

// camel-k: language=java dependency=camel-git
import org.apache.camel.builder.RouteBuilder;

public class Gitlab extends RouteBuilder {
  @Override
  public void configure() throws Exception {

    from("git:///tmp/config-service?remotePath=https://xxx&branchName=master&type=branch&username=xxx&password=xxx")
    .transform().constant("checked-out").to("log:info");

  }
}

But this gives the below permission error. When logged into the pod and tried to create a file or folder inside the deployment directory its giving a permission error. Is there any way to set the User inside the container with Traits or any other method?

Answer 1

There are 2 parts in fixing this problem.

Firstly to work around the XDG_CONFIG_HOME problem, you can set a environment variable for the integration like:

kamel run -e XDG_CONFIG_HOME=/tmp/.config Gitlab.java

Second, the camel-git consumer can only do simple tasks on an existing Git repository like listing branches, tags & commits. To clone a repository you need to use the producer like:

to(git:///tmp/config-service?remotePath=https://github.com/apache/camel-k.git&branchName=master&operation=clone")
