saltlab

Personal Saltstack lab environment in Docker (Centos7 containers)

Contact: Robert Nowotniak [email protected]

Tested on ArchLinux as the Docker host.

Quick start

git clone https://github.com/rnowotniak/saltlab
docker pull rnowotniak/saltlab

cd saltlab
docker-compose up

Enter the Salt master container, accept all minions keys:

docker exec -it salt1 bash -l
salt-key
salt-key -A -y

Run some tests from Salt master to the minions:

salt '*' test.ping

Change number of minions dynamically:

docker-compose up --scale minions=6

---

Some useful commands:

docker pull centos:centos7
docker run -it --rm centos:centos7

yum install salt-master
yum install salt-minion

vi /etc/salt/minion  (update master: hostname)

/usr/bin/salt-master -d
/usr/bin/salt-minion -d -l info

tail /var/log/salt/{master,minion}

salt-key
salt-key -A


docker build -t rnowotniak/saltlab .
docker run --name salt1 --rm rnowotniak/saltlab

docker-compose
up  ( -d )
scale minions=3
logs master
ps
restart minions
