[bug] .bashrc updated in wrong user

[dougbtv]

Bashrc is being updated in the /home/centos user every time, likely it's missing the variable.

Here's the culprit:

roles/kube-cni/defaults/main.yml:3:kubectl_home: /home/centos

I don't get what the issue is in this bug :)

[dougbtv]

The gist is, if you're using a user other than centos -- which works for 90% of the time, if you've brought your own deployment that doesn't have a centos user, this doesn't follow the construct we use elsewhere. e.g. in this line in a defaults file it reads a static:

kubectl_home: /home/centos

Whereas in other files, such as this example, we use something like:

dest: "{{ ansible_env.HOME }}/{{ gopath }}/github.com/opencontainers/runc"

So if you are using a different user -- you'll never be able to issue a kubectl command later in the playbooks

[leifmadsen]

Would you suggest we just drop the use of kubectl_home everywhere and replace with ansible_env.HOME instead?

This is used in a few spots (just doing a quick grep). The following is the list of roles using it:

• kube-init
• kube-install
• kube-teardown
• kube-cni

I think that'd probably work great, I think the kubectl_home variable is a hangover from earlier iterations before some of this stuff got standardized, and likely it was a variable lofted into a default from group_vars/all and just kinda got lost in the shuffle.
