Environment

All Supported Releases

Cause

During a non-root installation, there is an additional variable required to specify the keys directory for the non-root user.

Resolution

For a root installation, launching the deployment container will use the below command:

docker run \
--rm \
-e ANSIBLE_CONFIG=/root/k8s-installer/scripts/ansible/ansible.cfg \
-e LANG=en_US.UTF-8 \
-v $HOME/k8s-installer:/root/k8s-installer \
-v $HOME/.ssh:/root/.ssh \
-v $HOME/.kube:/root/.kube \
-v /etc/ssl/certs/:/etc/ssl/certs/ \
-v /etc/docker/:/etc/docker/ \
--network host \
-it localhost/deployment:2.8.0-944 \
bash

For a non-root installation (netopsadmin is the user in this case), users will need to add the line in bold:

sudo docker run \
--rm \
-e ANSIBLE_CONFIG=/root/k8s-installer/scripts/ansible/ansible.cfg \
-e LANG=en_US.UTF-8 \
-v $HOME/k8s-installer:/root/k8s-installer \
-v $HOME/.ssh:/root/.ssh \
-v $HOME/.kube:/root/.kube \
-v /etc/ssl/certs/:/etc/ssl/certs/ \
-v /etc/docker/:/etc/docker/ \
-v /home/netopsadmin/.ssh:/home/netopsadmin/.ssh:ro \
--network host \
-it localhost/deployment:2.8.0-944 \
bash
