Thank you. - -------------------------- INTERMISSION -------------------------- - - -Procedure, Part Two of Two: - - 1) When 'test_build_cache_images' completes, click it, then click - 'View more details on Cirrus CI', then expand the 'Run build_vm_image' - accordion. This gives you a garishly colorful display of lines. - Each color is a different VM. - - 2) Verify that each VM has the packages you require. (The garish log - doesn't actually list this for all packages, so you may need to - look in the 'verify_test_built_images' log for each individual - VM. Click the 'package_versions' accordion.) - - 3) At the bottom of this log you will see a block like: - - Builds finished. The artifacts of successful builds are: - ubuntu-19: A disk image was created: ubuntu-19-podman-6439450735542272 - fedora-31: A disk image was created: fedora-31-podman-6439450735542272 - ..... - - The long numbers at the end should (MUST!) be all identical. - - 4) Edit .cirrus.yml locally. Find '_BUILT_IMAGE_SUFFIX' near the - top. Copy that long number ("6439450735542272", above) and paste - it here, replacing the previous long number. - - 5) Wait for CI to turn green. I know you might have skipped that, - because 'test_build_cache_images' finishes long before 'verify', - and maybe you're in a hurry, but come on. Be responsible. - - 6) Edit the PR description in github: remove '[CI:IMG]' from the - title. Again, *in github*, in the web UI, use the 'Edit' button - at top right next to the PR title.

But other operating systems can use the “remote client” to manage their containers to a Linux backend. This remote client is nearly identical to the standard Podman program. Certain functions that do not make sense for remote clients have been removed. For example, the “--latest” switch for container commands has been removed. + +### Brief architecture + +The remote client uses a client-server model. You need Podman installed on a Linux machine or VM that also has the SSH daemon running. On the local operating system, when you execute a Podman command, Podman connects to the server via SSH. It then connects to the Podman service by using systemd socket activation. The Podman commands are executed on the server. From the client's point of view, it seems like Podman runs locally. + +## Obtaining and installing Podman + +### Windows + +Installing the Windows Podman client begins by downloading the Podman windows installer. The windows installer is built with each Podman release and is downloadable from its [release description page](https://github.com/containers/podman/releases/latest). You can also build the installer from source using the `podman.msi` Makefile endpoint. + +Once you have downloaded the installer, simply double click the installer and Podman will be installed. The path is also set to put `podman` in the default user path. + +Podman must be run at a command prompt using the Windows ‘cmd” or powershell applications. + +### MacOS + +The Mac Client is available through [Homebrew](https://brew.sh/). You can download homebrew via the instructions on their site. Install podman using: +``` +$ brew install podman +``` + +## Creating the first connection + +### Enable the Podman service on the server machine. + +Before performing any Podman client commands, you must enable the podman.sock SystemD service on the Linux server. In these examples, we are running Podman as a normal, unprivileged user, also known as a rootless user. By default, the rootless socket listens at `/run/user/${UID}/podman/podman.sock`. You can enable this socket, permanently using the following command: +``` +$ systemctl --user enable podman.socket +``` +You will need to enable linger for this user in order for the socket to work when the user is not logged in. + +``` +$ sudo loginctl enable-linger $USER +``` + +You can verify that the socket is listening with a simple Podman command. + +``` +$ podman --remote info +host: + arch: amd64 + buildahVersion: 1.16.0-dev + cgroupVersion: v2 + conmon: + package: conmon-2.0.19-1.fc32.x86_64 +``` + +#### Enable sshd + +In order for the client to communicate with the server you need to enable and start the SSH daemon on your Linux machine, if it is not currently enabled. +``` +$ sudo systemctl enable -s sshd +``` + +#### Setting up SSH +Remote podman uses SSH to communicate between the client and server.
