saml2aws Docker image, updated to work with symlink and get latest version

saml2aws Docker image

Due to the flakyness of Linux keyrings, saml2aws may get deadlocked. To get around this issue, saml2aws can be run in a Docker container. This Gist contains a Dockerfile and a helper script to use as drop-in replacement for saml2aws.

1. Clone this Gist: https://gist.github.com/b5f76044eba1855b4222111b12a76dab.git

2. Make the saml2aws.sh script executable:

   $ chmod +x /path/to/the/cloned/gist/saml2aws.sh
   

3. Link the saml2aws.sh script to somewhere in your path. E.g.:

   $ ln -s /path/to/the/cloned/gist/saml2aws.sh ~/.local/bin/saml2aws
   

You should now be able to run saml2aws. The container will be automatically built, if it hasn't been built already.
