Building Docker Image

docker build -t praison/ansible-packer-terraform .

Examples getting versions

docker run --rm praison/ansible-packer-terraform terraform -version
docker run --rm praison/ansible-packer-terraform packer -version
docker run --rm praison/ansible-packer-terraform ansible --version
docker run --rm praison/ansible-packer-terraform aws --version

Bash Integration

Add it to

.bashrc or .bash_profile

It also maps your .ssh and .aws folders to share keys and configs that the command might need.

pansible () 
{
  docker run --rm \
             -w /opt \
             -v $(pwd):/opt/ \
             -v ~/.aws:/root/.aws \
             -v ~/.ssh:/root/.ssh \
             praison/ansible-packer-terraform ansible $@
}

paws () 
{
  docker run --rm \
             -w /opt \
             -v $(pwd):/opt/ \
             -v ~/.aws:/root/.aws \
             -v ~/.ssh:/root/.ssh \
             praison/ansible-packer-terraform aws $@
}

ppacker () 
{
  docker run --rm \
             -w /opt \
             -v $(pwd):/opt/ \
             -v ~/.aws:/root/.aws \
             -v ~/.ssh:/root/.ssh \
             praison/ansible-packer-terraform packer $@
}

pterraform () 
{
  docker run --rm \
             -w /opt \
             -v $(pwd):/opt/ \
             -v ~/.aws:/root/.aws \
             -v ~/.ssh:/root/.ssh \
             praison/ansible-packer-terraform terraform $@
}

Example usage:

$ ppacker -version
1.5.4

$ pansible --version
ansible 2.5.1
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/dist-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.17 (default, Nov  7 2019, 10:07:09) [GCC 7.4.0]
