Elasticluster and docker installation - centos7

[Maiken Pedersen]

Hi,

I wanted to add docker ce to the worker nodes and using  elasticluster version 1.3.dev26 I get:

TASK [docker-ce : Fail if base OS not supported] *******************************************************************************************************************************
fatal: [compute001]: FAILED! => {"msg": "The conditional check 'not is_rhel7_or_later' failed. The error was: error while evaluating conditional (not is_rhel7_or_later): 'is_rhel7_or_later' is undefined\n\nThe error appears to be in '/home/centos/elasticluster/src/elasticluster/share/playbooks/roles/docker-ce/tasks/init-RedHat.yml': line 3, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: 'Fail if base OS not supported'\n  ^ here\n"}

I am using Centos7 image for the (openstack) cluster.

is_rhel7_or_later variable seems not to be defined?

Hello Maiken,

thanks for spotting this issue!  Should be fixed now, in the "master" branch and in the Docker image 1.3.dev28

(It was just a typo, should have been `is_rhel7_or_later_compatible`)

Ciao,

Spotted another issue.

Now on 1.3dev28:

TASK [docker-ce : Install Docker Community Edition] **************************************************************************************************************************************************
[WARNING]: Updating cache and auto-installing missing dependency: python-apt
fatal: [compute002]: FAILED! => {"changed": false, "cmd": "apt-get update", "msg": "[Errno 2] No such file or directory", "rc": 2}
fatal: [compute001]: FAILED! => {"changed": false, "cmd": "apt-get update", "msg": "[Errno 2] No such file or directory", "rc": 2}

It tryes apt-get although I am on Centos7

Best,

Maiken
