Anmsible and Docker are tool to deploy software in Azure, e.g. PostgreSQL deployment in Azure.

Ansible

• Make fresh linux vm, must be 64 bit for Docker.
  
  • If you run Windows, install virtualbox or VMware to host a virtual Linux machine. Manually load a downloaded Linux image inside virtualbox: http://askubuntu.com/questions/64915/how-do-i-install-ubuntu-on-a-virtualbox-client-from-an-iso-image
    • Ubuntu http://releases.ubuntu.com/16.04/ around Debian.
      
    • CentOS (free version of RedHat) https://www.centos.org/download/
    • Inside virtualbox: forward 2222 to 22 to be able to use putty
  • If you run a Linux machine, use vagrant (from linux box / terminal)
  • During installlation, tick openssh,.. If you forgot, afterwards do apt-get install openssh -server
• Standard python 2.7.12 is sufficient for Ansible
• Install Ansible (and if needed git)

sudo apt-get update
sudo apt-get install ansible
sudo apt-get install git

• Check whether Ansible installed, e.g. with check version: 2.0.0.2

 ansible --version

• Test

ansible all -i "localhost," -c local -m shell -a 'echo hello world'

• Make essential files to test Ansible
  

  • inventory (name can be different, but this is convention)

    [local] 
    localhost ansible_connection=local

  • playbook.yml (name can be different, but this is convention)

    ---
    - name: Hello Ansible - quick start
      hosts: all
    
      tasks:
        - name: add current date to now.txt file
          shell: date >> now.txt 

Run ansible-playbook

ansible-playbook playbook.yml --inventory inventory --user `whoami`
# or in short format:
ansible-playbook playbook.yml -i inventory -u `whoami`

Docker

Install docker to be able to run docker images. See also: https://github.com/openearth-stack/general/blob/master/testing.md

sudo apt-get install docker.io
# add user, see git
# docker run -it quay.io/travisci/travis-ruby /bin/bas

Become a member of the docker group

sudo usermod -aG docker $(whoami)
# or alternatives to manually add your username to
# docker:x:117:USERNAME
# >> vigr
# >> sudo nano /etc/group

Exit and log back to to make these changes effective. Create a shadow group

vigr -s

Run docker to install for instance a postgres container (https://hub.docker.com/_/postgres/)

docker run --name some-postgres -e POSTGRES_PASSWORD=mysecretpassword -d postgres

You can see the container in

sudo ls /var/lib/docker/containers

YOu can run a second docker that talks to the first (using mysecretpassword)

docker run -it --rm --link some-postgres:postgres postgres psql -h postgres -U postgres
