Run phpmyadmin with docker through UNIX sockets on localhost

phpmyadmin.sh

# Run phpmyadmin with docker on your localhost (minimal configuration)
docker run -d -p 8080:80 \
           --name phpmyadmin \
           -e "PMA_HOST=localhost" \
           -v /var/run/mysqld/mysqld.sock:/tmp/mysql.sock \
           phpmyadmin/phpmyadmin
           
# if you want autologin replace PMA_USER and PMA_PASSWORD
# warning: you're opening the database to the world if you're not behind a firewall
docker run -d -p 8080:80 \
           --name phpmyadmin \
           -e "PMA_HOST=localhost" \
           -e "PMA_USER=root" \
           -e "PMA_PASSWORD=1234" \
           -v /var/run/mysqld/mysqld.sock:/tmp/mysql.sock \
           phpmyadmin/phpmyadmin

# Once created you can stop, run and remove the container as you want, it's yours.
docker stop phpmyadmin
docker start phpmyadmin
docker rm phpmyadmin

It seems that there is a non documented PMA_SOCKET env var that you can use instead of PMA_HOST to specify the path to the socket.

You could run something like:

docker run -d -p 8080:80 \
           --name phpmyadmin \
           -e "PMA_SOCKET=/tmp/mysql.sock" \
           -v /var/run/mysqld/mysqld.sock:/tmp/mysql.sock \
           phpmyadmin/phpmyadmin
