Self hosted action fails on linux.sh

[Steveb-p]

When trying to build and run a github runner using the docs: https://github.com/shivammathur/setup-php/wiki/Dockerized-self-hosted-runner-on-Ubuntu

I keep getting an error:

Run shivammathur/setup-php@2.9.0
  with:
    php-version: 7.4
    coverage: none
    extensions: pdo_sqlite, gd
    tools: cs2pr
  env:
    runner: self-hosted
Error: EACCES: permission denied, open '/opt/hostedtoolcache/linux.sh'

Is the setup-php on self hosted still supported?

[shivammathur]

Yes, it is supported.
Can you provide your Dockerfile for testing.

@shivammathur haven't really changed it much from the docs: (COPY I've added later on - isn't working both with and without it)

FROM shivammathur/node:focal-slim
# ubuntu:focal, ubuntu:bionic and ubuntu:xenial would also work
# shivammathur/node docker images are optimised for setup-php

To give a little more context.

I've tried finding the issue yesterday thinking it's something on my own machine (since I wasn't able to find any issues where /opt/hostedtoolcache pops up).

I've made sure that I'm working on a fresh docker image when/if applying changes to Dockerfile, and I was using a fresh container instance each time I've tried something.

I've looked if the /opt/hostedtoolcache is mentioned anywhere in the setup-php repository, but it isn't.

The GH action on github runner works flawlessly.

I can copy and chmod the scripts to try (haven't yet) to make it work, but I believe those scripts should be added by the action during it's runtime / cached, not permanently added into the docker image.

[Steveb-p]

With the following Dockerfile with scripts coming from your setup-php repository the runner works fine:

FROM shivammathur/node:focal-slim
# ubuntu:focal, ubuntu:bionic and ubuntu:xenial would also work
# shivammathur/node docker images are optimised for setup-php

  && usermod -aG sudo runner \
  && mkdir -m 777 -p /home/runner \
  && sed -i 's/%sudo\s.*/%sudo ALL=(ALL:ALL) NOPASSWD : ALL/g' /etc/sudoers

COPY ./src/scripts/ /opt/hostedtoolcache/

RUN chmod -R 777 /opt/hostedtoolcache

USER runner
WORKDIR /home/runner

RUN sudo curl -o runner.tar.gz -sSL https://github.com/actions/runner/releases/download/v${RUNNER_VERSION}/actions-runner-linux-x64-${RUNNER_VERSION}.tar.gz \
  && sudo tar xf runner.tar.gz \
  && sudo bash ./bin/installdependencies.sh || true

CMD [ "bash", "-c", "./config.sh --url ${RUNNER_URL} --token ${RUNNER_TOKEN}; ./run.sh; sleep infinity"]

[shivammathur]

I have patched this in shivammathur/node-docker@174a323
Pull shivammathur/node:focal-slim image again and then rebuild your runner docker image. It should work correctly.

docker pull shivammathur/node:focal-slim

# Follow Build and Run steps from the wiki

docker build -t linuxselfhosted:0.2 --build-arg RUNNER_VERSION=1.2.3 .
docker run -it -e RUNNER_URL=https://github.com/foo/bar -e RUNNER_TOKEN=ABCDEFGHIJKLNMOPQRSTUVWXYZABC linuxselfhosted:0.1

In next release, I would figure out if I can find a better solution so that setup-php handles it.

[Steveb-p]

This indeed allowed my runner to work. Thanks 🍺
