在不使用bash -c的docker run中使用容器环境变量

Question

I have a WP-CLI container where I have to run the following command:

wp --allow-root core config --dbname=$MYSQL_DATABASE --dbuser=$MYSQL_USER --dbpass=$MYSQL_PASSWORD --dbhost=$WP_CLI_MYSQL_HOST --debug

When I run in bash inside container, I have no problem, but when I try to do:

docker-compose run --rm wordpress-cli --rm core config --dbname=$MYSQL_DATABASE --dbuser=$MYSQL_USER --dbpass=$MYSQL_PASSWORD --dbhost=$WP_CLI_MYSQL_HOST --allow-root --debug

All environment variables are evaluated in the host instead of the container, so they are passed empty to container.

I found in this question , that using bash -c 'my command' will do the trick, but my ENTRYPOINT is the WP command, so I want to just run without using the bash command.

只需转义$它们传递到容器：

docker-compose run --rm wordpress-cli --rm core config --dbname=\$MYSQL_DATABASE --dbuser=\$MYSQL_USER ...
