Here is my Dockerfile

```
FROM node:10

RUN apt-get -qq update && apt-get -qq -y install bzip2

RUN yarn global add @bluebase/cli && bluebase plugins:add @bluebase/cli-expo && bluebase plugins:add @bluebase/cli-web
RUN bluebase plugins

```

When the docker file is built it installs all dependencies, and the last command `RUN bluebase plugins` outputs the list of plugins installed. But when this image is pushed and used in github actions, `bluebase` is available globally but no plugins are installed. What am I doing wrong?

Github Workflow
