Execute script inside docker container which is folder different than WORKDIR

Question

I'm inside my docker container: This is my working directory

root@19b84a014662:/usr/src/ghost#

I have a script in:

root@19b84a014662:/

I'm able to cd to / and execute the script. But I need to execute the script from my docker-compose file. I tried

./test.sh

But this actually means it's searching in /usr/src/ghost/ for the script instead of / How can I execute the script, in the / of my container?

Example: I ssh into my container:

root@19b84a014662:/usr/src/ghost# ls
Gruntfile.js  LICENSE  PRIVACY.md  README.md  config.example.js  config.js  content  core  index.js  node_modules  npm-shrinkwrap.json  package.json

I have a script in the root of my container. I want to execute it with:

./test.sh

Than it show me only folders/scripts which are in /usr/src/ghost and not in /

root@19b84a014662:/usr/src/ghost# ./
content/      core/         node_modules/

Answer 1

Just replace your ./test.sh by

/test.sh

Because ./ means you're starting from current directory (which is the working dir /usr/src/ghost/ in this case). Inspite of this / means you're starting from root directory and that's what you want to do.

Alternatively you could switch to root dir and execute your script in one command using the && concatenator below. But I'll recommend the above.

cd / && ./test.sh
