“apb list”: Exception occurred! [Errno 2] No such file or directory: '/root/.kube/config'

Dear author:
I need your help. I have commented the condition "apb should not be run as root" in apb-docker-run.sh , because I have to run docker with root user (without considering about security in my experimental env). And I have run "apb init apb-demo && cd apb-demo && apb build " successfully. But I got exception when executing "apb list", "apb bootstrap" and so on. I have already logged in openshift with cluster-admin role . The following are some shell cmds and output:

[root@localhost data]# apb init apb-demo

Edit the script again, and in the place where it says -u $UID put -u 1000 . If that works well I'll send a patch to fix it, like in this one here

ansible-playbook-bundle/scripts/apb-docker-run.sh

Line 46 in 52cff6f

-u $UID $APB_IMAGE "$@"

I run into the same problem, and I can confirm this fixed the issue.

Cheers

The more elegant solution is just add the KUBECONFIG variable to match the volume path

-e KUBECONFIG=/.kube/config

And that will work with any $UID and will prevent errors like if the $HOME/.kube dir ownership is by uid
which is not 1000.
