Unable to start a MySQL Container & attach it to the Docker network

Question

I am following Docker Labs tutorial & have made it to the 7th step. Where I need to Attach MySQL DB container to my app network container. Upon entering the following command on windows 10 CMD:

docker run -d \
--network todo-app --network-alias mysql \
-v todo-mysql-data:/var/lib/mysql \
-e MYSQL_ROOT_PASSWORD=secret \
-e MYSQL_DATABASE=todos \
mysql:5.7

I get this error:

C:\Users\Ajmal .M\getting-started>docker run -d \
docker: invalid reference format.
See 'docker run --help'.

C:\Users\Ajmal .M\getting-started>    --network todo-app --network-alias mysql \

Answer 1

The reason you're getting this error is because it's trying to run each line as an individual command instead of one docker command.

On windows instead of \\ for a new line use ^

docker run -d ^
--network todo-app --network-alias mysql ^
-v todo-mysql-data:/var/lib/mysql ^
-e MYSQL_ROOT_PASSWORD=secret ^
-e MYSQL_DATABASE=todos ^
mysql:5.7

The command above is the same as this one line command:

docker run -d --network todo-app --network-alias mysql -v todo-mysql data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=secret -e MYSQL_DATABASE=todos mysql:5.7
