The WSL podman machine image builds have been merged into our main [podman-machine-os](https://github.com/containers/podman-machine-os) repository starting with v5.6 images. Please report new issues there instead. 4 | 5 | [![Cirrus CI - Default Branch Build Status](https://img.shields.io/cirrus/github/containers/podman-machine-wsl-os)](https://cirrus-ci.com/github/containers/podman-machine-wsl-os) 6 | 7 | # Podman Machine WSL OS 8 | 9 | Source code to build and release the Fedora-based VM image for WSL. 10 | 11 | The image is distributed as a [zstd compressed](https://facebook.github.io/zstd/) `.tar` file for both `amd64` and `arm64` architectures. 12 | 13 | The CI is triggered every 3 hours **and** at every push to the main branch. 14 | 15 | At every update of the disk image: 16 | - a new OCI artifact is pushed to [quay.io/podman/machine-os-wsl](https://quay.io/repository/podman/machine-os-wsl?tab=tags) 17 | 18 | ## Build Process Details 19 | 20 | The source code that builds the WSL image for podman is in this [Cirrus CI manifest](https://github.com/containers/podman-machine-wsl-os/blob/main/.cirrus.yml). 21 | 22 | To build the content of the Fedora-based disk the CI execute the following steps: 23 | - Pulls the latest `docker.io/library/fedora` 24 | - Starts a container named `fedora-update` and execute the commands to install Podman and other packages 25 | 26 | After that, if the are no changes compared to the last time the CI has been executed (i.e. neither the `docker.io/library/fedora` image nor Podman and other packages have been updated), the build stops. When there are some changes, then a new image disk is built: 27 | - Export the `fedora-update` container content to the file `rootfs.tar` (`podman export --output rootfs.tar fedora-update`) 28 | - Remove the content of the file `/etc/resolv.conf` in `rootfs.tar` and compress it using zstd 29 | 30 | If at least one of the 2 images (`amd64` and `arm64`) has been updated then the CI publishes a new release: 31 | - Creates [a new GitHub release](https://github.com/containers/podman-machine-wsl-os/releases), using the build timestamp as version, and uploads the 32 | - Push the OCI artifact to [quay.io/podman/machine-os-wsl](https://quay.io/repository/podman/machine-os-wsl?tab=tags) using the next version of Podman as the image tag 33 | 34 | That's done for both `amd64` and `arm64` architectures. And v5.1 and v5.2 zstd files are identical. 35 | 36 | ## The Delay with Podman Releases 37 | 38 | WSL disk images build is disconnected to Podman release process. 39 | 40 | The WSL disk image build is triggered every 3 hours and it looks for a new version of Podman. But it looks for an update on Fedora stable and that's usually updated a few days after a Podman release. 41 | 42 | For example [Podman v5.2.2 has been released on the 2024-08-21](https://github.com/containers/podman/releases/tag/v5.2.2) but [has been included in Fedora 40 stable](https://bodhi.fedoraproject.org/updates/FEDORA-2024-435a743cf7) one week after that, and the updated WSL disk image [has been released on the 2024-08-27](https://github.com/containers/podman-machine-wsl-os/releases/tag/v20240827181401). 43 | 44 | ## When a new dev version of Podman is bumped on main branch 45 | 46 | Before bumping the version of Podman in c/podman, the corresponding WSL image should be pushed to quay.io: 47 | 48 | ```diff 49 | - IMAGE_TAG_DEV: "5.4" 50 | + IMAGE_TAG_DEV: "5.5" 51 | ``` 52 | 53 | ## When a new version of Podman is released 54 | 55 | After a new version of Podman has been released (i.e. when the fedora package has been updated), the OCI artifact tags should be updated using development Podman version: 56 | 57 | ```diff 58 | - IMAGE_TAG_LATEST: "5.3" 59 | - IMAGE_TAG_NEXT: "5.4" 60 | + IMAGE_TAG_LATEST: "5.4" 61 | + IMAGE_TAG_NEXT: "5.5" 62 | ``` 63 | 64 | Note that at that point `IMAGE_TAG_NEXT` and `IMAGE_TAG_DEV` will match. 65 | -------------------------------------------------------------------------------- /.cirrus.yml: -------------------------------------------------------------------------------- 1 | env: 2 | IMAGE_TAG: 41 3 | GITHUB_SERVER_URL: "https://github.com" 4 | CIRRUS_SHELL: bash 5 | IMAGE_SUFFIX: "c20250131t121915z-f41f40d13" 6 | FEDORA_AARCH64_AMI: "fedora-podman-aws-arm64-${IMAGE_SUFFIX}" 7 | FEDORA_AMI: "fedora-aws-${IMAGE_SUFFIX}" 8 | PCURL_RETRY: "curl --retry 5 --retry-delay 8 --retry-all-errors -L" 9 | PACKAGE_LIST: "procps-ng openssh-server net-tools iproute dhcp-client crun-wasm wasmedge-rt qemu-user-static subscription-manager gvisor-tap-vsock-gvforwarder cifs-utils nfs-utils-coreos ansible-core iptables-nft" 10 | VER_PFX: "5.0" 11 | 12 | aws_credentials: ENCRYPTED[d8df25d9f680ea7b046e9883851355574913eb4bf7b89acc4efe8e039a4fc0112ade4469ff98d6a9a22285d495034905] 13 | 14 | build_task: 15 | alias: 'build' 16 | only_if: $CIRRUS_BRANCH == 'main' && $CIRRUS_PR == "" && $CIRRUS_TAG == "" 17 | auto_cancellation: true 18 | env: 19 | matrix: 20 | - BUILD_ARCH: "arm64" 21 | USE_AMI: $FEDORA_AARCH64_AMI 22 | USE_TYPE: "t4g.xlarge" 23 | - BUILD_ARCH: "amd64" 24 | USE_AMI: $FEDORA_AMI 25 | USE_TYPE: "t3.xlarge" 26 | LAST_IMAGE_FILE: $VER_PFX-latest-$BUILD_ARCH 27 | ROOTFS_FILE: $VER_PFX-rootfs-$BUILD_ARCH.tar.zst 28 | PCACHE_KEY: upload-$VER_PFX-$CIRRUS_BUILD_ID-$BUILD_ARCH 29 | name: "build-$VER_PFX-$BUILD_ARCH" 30 | execution_lock: "podman-wsl-fedora-build-$VER_PFX-$BUILD_ARCH" 31 | ec2_instance: 32 | image: $USE_AMI 33 | type: $USE_TYPE 34 | region: us-east-1 35 | architecture: $BUILD_ARCH 36 | clear_script: | 37 | $PCURL_RETRY -v -X "DELETE" "http://$CIRRUS_HTTP_CACHE_HOST/$PCACHE_KEY" 38 | get_script: | 39 | set +o verbose 40 | date >> changes 41 | podman image pull docker.io/library/fedora:$IMAGE_TAG 42 | imageDigest=`podman image inspect docker.io/library/fedora:$IMAGE_TAG --format {{.Digest}}` 43 | echo $imageDigest > "$LAST_IMAGE_FILE" 44 | echo "Fetching $GITHUB_SERVER_URL/$CIRRUS_REPO_FULL_NAME/releases/latest/download/$LAST_IMAGE_FILE" 45 | lastImage=`$PCURL_RETRY "$GITHUB_SERVER_URL/$CIRRUS_REPO_FULL_NAME/releases/latest/download/$LAST_IMAGE_FILE"` 46 | echo "Digest: $imageDigest" 47 | echo "Last: $lastImage" 48 | if [ "$lastImage" != "$imageDigest" ];
