FOSSTECH Notes

Typical saltstack stack setup requires installing salt-master and installing salt-minions into all the managed nodes. This task can be tedious when the number as the managed nodes increased. As long as the managed nodes are accessible via ssh from the master nodes, we can automate this task and deploy salt-minion using salt-ssh. In your salt-master run the following: # cd /srv/salt # mkdir -p deploysalt/conf # cd deploysalt Create a file called init.sls with the following content: Add_Repository:                                                                                                                                          pkgr...

I have been using vagrant to setup my demo system and I don't really like how vagrant setup my virtual machine so I did few changes to it. I need my virtual machines to be able to interact with each other so I will need my virtual machines to be bridged. I also like to interact using standard ssh using password instead of using vagrant ssh, so my setup will enable password based ssh and disable vagrant ssh. My environment router is 192.168.100.254 so you will need to adjust the file a little bit to your environment. Create a directory to contain your virtual machine: # mkdir node01 # cd node01 Create a file called Vagrantfile containing the following:   Vagrant.configure("2") do |config|   # Use SUSELeap 15.0  config.vm.box = "opensuse/openSUSE-15.0-x86_64"  # Configure Hostname and Public IP Address  config.vm.hostname = "node01"  config.vm.network "public_network", bridge:"eth0", ip:"192.168.100.51" ...

Whenever I need to quickly setup some demo system on my laptop, vagrant has been my go to tools. vagrant packages can be found in the following repositories: http://download.opensuse.org/repositories/Virtualization:/vagrant/openSUSE_Leap_15.0/ By default, vagrant works well with virtualbox which is currently part of default openSUSE Leap 15.0. Install virtualbox and add your current user to vboxusers. Assuming your username is called testuser, run the following command: > sudo zypper in virtualbox > sudo usermod -G vboxusers testuser Logout and re-login again so that your OS reload user group information. You can verify that your user belongs to vboxusers by running the following command: > id Now the system is ready for vagrant. Add the repo above and install vagrant > sudo zypper in vagrant I usually make a separate directory to keep my demo environment. > mkdir vagrant > cd vagrant You can easily download and startup another openSUSE Lea...
