# Executes the provided arguments as a shell command with a twist: if mysql is
# not already running: starts mysql, runs the commands, and stops mysql.
# Example usage:
# - mysqldo mysql -u root -p # will open an interactive shell and will stop mysql
#                            # when you leave the shell
# - mysqldo 'echo "show databases;" | mysql -u root -p"my_password"'
#   # note that if your commands involve pipes or anything that the shell
#   # interpretter would not pass to mysqldo as arguments, you should wrap the
#   # entire command in quotes.

This is an example of using Linux Kernel's Transparent Proxy to route all TCP traffic to docker containers without having to resort to PROXY protocol which is not supported by some applications (e.g. sshd). To get the demo to work you only need vagrant installed:

git clone [this-gist] tproxy-demo
cd tproxy-demo
vagrant up

POC simple HTTP monitoring script. First build the docker images:

git clone [this-gist] monitor
cd monitor
docker build -t amirkdv/monitor .

Now start the container, and all sites under sites.yaml will be pinged one after another:

docker run -i -t amirkdv/monitor
