It can be used with your existing process monitoring tools and the container will be spawned as a direct child of the process supervisor. Containers are configured using bundles. A bundle for a container is a directory that includes a specification file named "config.json" and a root filesystem. The root filesystem contains the contents of the container. To start a new instance of a container: # runc run [ -b bundle ] Where "" is your name for the instance of the container that you are starting. The name you provide for the container instance must be unique on your host. Providing the bundle directory using "-b" is optional. The default value for "bundle" is the current directory.

The spec generated is just a starter file. Editing of the spec is required to achieve desired results. For example, the newly generated spec includes an args parameter that is initially set to call the "sh" command when the container is started. Calling "sh" may work for an ubuntu container or busybox, but will not work for containers that do not include the "sh" program. EXAMPLE: To run docker's hello-world container one needs to set the args parameter in the spec to call hello. This can be done using the sed command or a text editor. The following commands create a bundle for hello-world, change the default args parameter in the spec from "sh" to "/hello", then run the hello command in a new hello-world container named container1: mkdir hello cd hello docker pull hello-world docker export $(docker create hello-world) > hello-world.tar mkdir rootfs tar -C rootfs -xf hello-world.tar runc spec sed -i 's;"sh";"/hello";' config.json runc run container1 In the run command above, "container1" is the name for the instance of the container that you are starting. The name you provide for the container instance must be unique on your host. An alternative for generating a customized spec config is to use "oci-runtime-tool", the sub-command "oci-runtime-tool generate" has lots of options that can be used to do any customizations as you want, see runtime-tools (https://github.com/opencontainers/runtime-tools) to get more information. When starting a container through runc, runc needs root privilege. If not already running as root, you can use sudo to give runc root privilege. For example: "sudo runc start container1" will give runc root privilege to start the container on your host. Alternatively, you can start a rootless container, which has the ability to run without root privileges. For this to work, the specification file needs to be adjusted accordingly. You can pass the parameter --rootless to this command to generate a proper rootless spec file. Note that --rootless is not needed when you execute runc as the root in a user namespace created by an unprivileged user. OPTIONS: --bundle value, -b value path to the root of the bundle directory --rootless generate a configuration for a rootless container lets create link sangam@sangam:~/runc-sangam-demo$ sudo runc create --bundle . container1 sangam@sangam:~/runc-sangam-demo$ sudo runc list ID PID STATUS BUNDLE CREATED OWNER container1 379391 created /home/sangam/runc-sangam-demo 2024-02-08T16:08:52.31926604Z root list all namespaces link sangam@sangam:~/runc-sangam-demo$ sudo lsns NS TYPE NPROCS PID USER COMMAND 4026531834 time 221 1 root /sbin/init 4026531835 cgroup 220 1 root /sbin/init 4026531836 pid 208 1 root /sbin/init 4026531837 user 221 1 root /sbin/init 4026531838 uts 217 1 root /sbin/init 4026531839 ipc 208 1 root /sbin/init 4026531840 net 220 1 root /sbin/init 4026531841 mnt 202 1 root /sbin/init 4026531862 mnt 1 25 root kdevtmpfs 4026532545 mnt 1 561 root /lib/systemd/systemd-udevd 4026532546 uts 1 561 root /lib/systemd/systemd-udevd 4026532626 mnt 1 714 systemd-timesync /lib/systemd/systemd-timesyncd 4026532627 uts 1 714 systemd-timesync /lib/systemd/systemd-timesyncd 4026532628 mnt 1 821 systemd-network /lib/systemd/systemd-networkd 4026532629 mnt 1 823 systemd-resolve /lib/systemd/systemd-resolved 4026532660 mnt 1 2373 65535 /pause 4026532661 ipc 12 2373 65535 /pause 4026532662 pid 1 2373 65535 /pause 4026532663 mnt 11 2662 root /usr/local/bin/runsvdir -P /etc/service/enabled 4026532664 pid 11 2662 root /usr/local/bin/runsvdir -P /etc/service/enabled 4026532666 mnt 1 379391 root runc init 4026532667 uts 1 379391 root runc init 4026532668 ipc 1 379391 root runc init 4026532669 pid 1 379391 root runc init 4026532670 net 1 379391 root runc init 4026532713 mnt 1 869 root /lib/systemd/systemd-logind 4026532714 uts 1 869 root /lib/systemd/systemd-logind 4026532732 cgroup 1 379391 root runc init list of all running processes on your system, including details about the user running each process, CPU and memory usage, the process ID (PID), the parent process ID (PPID), and more. link sangam@sangam:~/runc-sangam-demo$ ps auxf USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 2 0.0 0.0 0 0 ?
