Research direction
Start with docs/tutorial/using-docker-compose and reproduce the listed docker run command in the stated Ubuntu WSL environment. Inspect the /app contents and the container output, focusing on why package.json is unavailable. Done means the app container starts without the reported error, or the tutorial documents the required correction.
Written by the indexing model from the issue text.
Description
I've followed the tutorial section "using-docker-compose" on Ubuntu 20.04.6 LTS on WSL.
When I run the below commands, the app container does not appear in the running container list; it just showed up being terminated as seen from the output of docker ps -a.
docker run -dp 3000:3000 \
-w /app -v "$(pwd):/app" \
--network todo-app \
-e MYSQL_HOST=mysql \
-e MYSQL_USER=root \
-e MYSQL_PASSWORD=secret \
-e MYSQL_DB=todos \
node:18-alpine \
sh -c "yarn install && yarn run dev"
The execution log of todo-app is
$
yarn install v1.22.19
