Install multiple extensions with config.yml

[cycotron69]

Hi, I'm running the latest Docker container image of code-server on my Linux box. I mount my own /.config/config.yml into the container for setup. However, I'm not able to figure out how to specify multiple extensions to be installed via the config.yml, or maybe it's just not possible? Below are what I've tried and the results.

---

when I try to specify multiple install-extension declarations, ex:

install-extension: timonwong.shellcheck
install-extension: mads-hartmann.bash-ide-vscode
install-extension: foxundermoon.shell-format

I get the duplicate error:

error duplicated mapping key in "/home/coder/.config/code-server/config.yaml" (6:1)

 5 | install-extension: timonwong.she ...
 6 | install-extension: mads-hartmann ...
-----^
 7 | install-extension: foxundermoon. ...

---

when I try to put all extension on the same line, ex:

install-extension: timonwong.shellcheck mads-hartmann.bash-ide-vscode foxundermoon.shell-format

I get the extension not found error:

Extension 'timonwong.shellcheck mads-hartmann.bash-ide-vscode foxundermoon.shell-format' not found

---

I also tried YAML format:

install-extension: 
  - timonwong.shellcheck
  - mads-hartmann.bash-ide-vscode
  - foxundermoon.shell-format

and got:

Extension 'timonwong.shellcheck,mads-hartmann.bash-ide-vscode,foxundermoon.shell-format' not found.
