wordpress docker exits immediately - mysql

Question

I’m trying to get wordpress up and running with docker on OSX 10.12.1...
First I start up mysql:
docker run --name dockermysql -e MYSQL_ROOT_PASSWORD=secret -e MYSQL_DATABASE=wordpress -e MYSQL_USER=wordpress -e MYSQL_PASSWORD=secret -d mysql:5
That seems to work fine:
$ docker ps -a
f7d1562def4a mysql:5 "docker-entrypoint.sh" 33 minutes ago Up 33 minutes 3306/tcp dockermysql
but then I try wordpress…
docker run --name dockerpress --link dockermysql:mysql -d wordpress --net="host" -e WORDPRESS_DB_USER=wordpress -e WORDPRESS_DB_PASSWORD=secret
and it seems like it exits immediately
$ docker ps -a
84cc4d2abb57 wordpress "docker-entrypoint.sh" 7 minutes ago Exited (2) 7 minutes ago dockerpress
f7d1562def4a mysql:5 "docker-entrypoint.sh" 33 minutes ago Up 33 minutes 3306/tcp dockermysql
Here are the results of docker inspect dockerpress:

Answer 1

For anyone still learning, like me, I found the better solution here was to use docker-compose as described in the docs here: https://docs.docker.com/compose/wordpress/
One nice thing about this, aside from the fact that it's way easier to deal with, is you can see all of your env variables to avoid mismatched variables between your db and wp server - which is what was causing my initial problem

Answer 2

It worked for me to pull image version 5.7 for mysql and wordpress the latest image version.
Manual who i created it:
---1. docker pull wordpress
---2. docker pull mysql:5.7
---3. docker run --name nwplm-database -e MYSQL_ROOT_PASSWORD=Pa$$w0rd -d mysql:5.7
---4. docker run --name nwplm-wordpress --link nwplm-database -p 8080:80 -e WORDPRESS_DB_HOST=nwplm-database:3306 -e WORDPRESS_DB_USER=root -e WORDPRESS_DB_PASSWORD=Pa$$w0rd -e WORDPRESS_DB_NAME=nwplm-wordpress -e WORDPRESS_TABLE_PREFIX=wp_ -d wordpress
---5. open localhost:8080 in your browser
