README.md

Configuring the builder.

Install prerequisites.

$ sudo dnf install podman podman-docker jq

Add services.

$ sudo cp self-hosted-builder/*.service /etc/systemd/system/
$ sudo systemctl daemon-reload

Download qemu-user-static image

# sudo docker pull docker.io/iiilinuxibmcom/qemu-user-static:6.1.0-1

Autostart the x86_64 emulation support.

$ sudo systemctl enable --now qemu-user-static

Rebuild the image

First build s390x builder image docker.io/pytorch/manylinuxs390x-builder, using following commands:

$ cd ~
$ git clone https://github.com/pytorch/pytorch
$ cd pytorch
$ git submodule update --init --recursive
$ GPU_ARCH_TYPE=cpu-s390x "$(pwd)/.ci/docker/manywheel/build.sh" manylinuxs390x-builder
$ docker image tag localhost/pytorch/manylinuxs390x-builder docker.io/pytorch/manylinuxs390x-builder:cpu-s390x
$ docker image save -o ~/manywheel-s390x.tar docker.io/pytorch/manylinuxs390x-builder:cpu-s390x

Next step is to build actions-runner image using:

$ cd self-hosted-builder
$ sudo docker build \
      --pull \
      -f actions-runner.Dockerfile \
      -t iiilinuxibmcom/actions-runner.<name> \
      .

If there are failures, ensure that selinux doesn't prevent it from working. In worst case, selinux can be disabled with setenforce 0.

Now prepare all necessary files for runner registration:

$ sudo mkdir -p /etc/actions-runner/<name>
$ sudo chmod 700 /etc/actions-runner/<name>
$ sudo /bin/cp <github_app_private_key_file> /etc/actions-runner/<name>/key_private.pem
$ sudo echo <github_app_id> | sudo tee /etc/actions-runner/<name>/appid.env
$ sudo echo <github_app_install_id> | sudo tee /etc/actions-runner/<name>/installid.env
$ sudo echo NAME=<worker_name> | sudo tee    /etc/actions-runner/<name>/env
$ sudo echo ORG=<github_org>   | sudo tee -a /etc/actions-runner/<name>/env
$ cd self-hosted-builder
$ sudo /bin/cp helpers/*.sh /usr/local/bin/
$ sudo chmod 755 /usr/local/bin/app_token.sh /usr/local/bin/gh_token_generator.sh

Autostart the runner.

$ sudo systemctl enable --now actions-runner@$NAME
