Docker Mastery

Assignment

1. Run a nginx, a mysql, and a httpd (apache) server
2. Run all of them --detach (or -d), name them with --name
3. nginx should listen on 80:80, httpd on 8080:80, mysql on 3306:3306
4. When running mysql, use the --env option (or -e) to pass in MYSQL_RANDOM_ROOT_PASSWORD=yes
5. Use docker container logs on mysql to find the random password it created on startup
6. Clean it all up with docker container stop and docker container rm (both can accept multiple names or ID’s)
7. Use docker container ls to ensure everything is correct before and after

Answers

# Run nginx container
docker container run --name nginx -p 80:80 -d nginx

# Run mysql container
docker container run --name mysql -p 3306:3306 -e MYSQL_RANDOM_ROOT_PASSWORD=yes -d mysql

# Run httpd container
docker container run --name httpd -p 8080:80 -d httpd

Retrieve the mysql’s random root password

docker container logs mysql | grep "ROOT PASSWORD"

Check containers status

docker container ls

Stop all running containers

docker container stop nginx mysql httpd

Remove containers

docker container rm nginx mysql httpd
