Use container environment variable in docker run without using bash -c -

-

i have wp-cli container have run following command:

wp --allow-root core config --dbname=$mysql_database --dbuser=$mysql_user --dbpass=$mysql_password --dbhost=$wp_cli_mysql_host --debug

when run in bash inside container, have no problem, when try 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 evaluated in host instead of container, passed empty container.

i found in this question, using bash -c 'my command' trick, entrypoint wp command, want run without using bash command.

just escape $ passed through container:

docker-compose run --rm wordpress-cli --rm core config --dbname=\$mysql_database --dbuser=\$mysql_user ...
