I am new to elasticluster and I apologise if I missed this:
***I need to configure for a Local Ubuntu 16.04 machine Slurm cluster.***
Master machine has elasticluster installed and docker container is up
(`elasticluster
version 1.3.dev2`)
`./elasticluster list` reports config successfully.
I have 20 machines in a Munge realm by sharing the same:
`/etc/munge/munge.key`
```bash
eighti@linuxpegasus:/etc/munge$ munge -n | ssh linuxcapture01 unmunge
eighti@linuxcapture01's password:
STATUS: Success (0)
ENCODE_HOST: linuxcapture01 (127.0.1.1)
ENCODE_TIME: 2018-04-09 16:58:22 +1200 (1523249902)
DECODE_TIME: 2018-04-09 16:58:26 +1200 (1523249906)
TTL: 300
CIPHER: aes128 (4)
MAC: sha1 (3)
ZIP: none (0)
UID: eighti (1000)
GID: eighti (1000)
LENGTH: 0
```
NTP source is synced (same output on all machines):
```bash
eighti@linuxpegasus:/etc/munge$ timedatectl
Local time: Mon 2018-04-09 17:02:47 NZST
Universal time: Mon 2018-04-09 05:02:47 UTC
RTC time: Mon 2018-04-09 05:02:47
Time zone: Pacific/Auckland (NZST, +1200)
Network time on: yes
NTP synchronized: yes
RTC in local TZ: no
```
User is the same on all machines
That same user is `sudo` on all machines:
```bash
eighti@linuxpegasus:/etc/munge$ grep -Po '^sudo.+:\K.*$' /etc/group
eighti,stage
```
Master machine has ssh pub_keys entered to `~/.ssh/know_hosts` from all
other machines
Ansible is used everyday successfully on these machines
I have a feeling I'm very close to being able to deploy a cluster once I
understand how to edit or replace the `.elasticluster/config` file
