It can be used to create and maintain -containers. The following tutorial will teach you how to set up Podman and perform some basic -commands with Podman. - -## Install Podman on Fedora -Many of the basic components to run Podman are readily available from the Fedora RPM repositories; the only -exception is Podman itself. In this section, we will help you install all the runtime and build dependencies -for Podman until an RPM becomes available. - -### Installing build and runtime dependencies -``` -# sudo dnf install -y git runc libassuan-devel golang golang-github-cpuguy83-go-md2man glibc-static \ - gpgme-devel glib2-devel device-mapper-devel libseccomp-devel \ - atomic-registries iptables skopeo-containers containernetworking-cni -``` -### Building and installing podman -``` -# git clone https://github.com/projectatomic/libpod/ ~/src/github.com/projectatomic/libpod -# cd !$ -# make -# sudo make install PREFIX=/usr -``` - - -## Familiarizing yourself with Podman - -### Running a sample container -This sample container will run a very basic httpd server that serves only its index -page. -``` -# sudo podman run -dt -e HTTPD_VAR_RUN=/var/run/httpd -e HTTPD_MAIN_CONF_D_PATH=/etc/httpd/conf.d \ - -e HTTPD_MAIN_CONF_PATH=/etc/httpd/conf \ - -e HTTPD_CONTAINER_SCRIPTS_PATH=/usr/share/container-scripts/httpd/ \ - registry.fedoraproject.org/f26/httpd /usr/bin/run-httpd -``` -Because the container is being run in detached mode, represented by the *-d* in the podman run command, podman -will print the container ID after it has run. - -### Listing running containers -The Podman *ps* command is used to list creating and running containers. -``` -# sudo podman ps -``` - -Note: If you add *-a* to the *ps* command, Podman will show all containers. - -### Executing a command in a running container -You can use the *exec* subcommand to execute a command in a running container. Eventually you will be able to -obtain the IP address of the container through inspection, but that is not enabled yet. Therefore, we will -install *iproute* in the container. Notice here that we use the switch **--latest** as a shortcut for the latest -created container. You could also use the container's ID listed during *podman ps* in the previous step or -when you ran the container. -``` -# sudo podman exec --latest -t dnf -y install iproute -# sudo podman exec --latest -t ip a -``` - -Note the IP address of the *ethernet* device. - -### Testing the httpd server -Now that we have the IP address of the container, we can test the network communication between the host -operating system and the container using curl. The following command should display the index page of our -containerized httpd server. -``` -# curl http://:8080 -``` - -### Viewing the container's logs -You can view the container's logs with Podman as well: -``` -# sudo podman logs --latest -``` - - -### Stopping the container -To stop the httpd container: -``` -# sudo podman stop --latest -``` -You can also check the status of one or more containers using the *ps* subcommand. In this case, we should -use the *-a* argument to list all containers. -``` -# sudo podman ps -a -``` - -### Removing the container -To remove the httpd container: -``` -# sudo podman rm --latest -``` -You can verify the deletion of the container by running *podman ps -a*. -## More information - -For more information on Podman and its subcommands, checkout the asciiart demos on the [README](https://github.com/projectatomic/libpod#commands) -page. -- cgit v1.2.3-54-g00ecf
