Namespaces article index

Here is a list of our series of introductory articles on namespaces:

• Namespaces in operation, part 1: namespaces overview
• Part 2: the namespaces API
  • demo_uts_namespaces.c: demonstrate the use of UTS namespaces
  • ns_exec.c: join a namespace using setns() and execute a command
  • unshare.c: unshare namespaces and execute a command; similar in concept to unshare(1)
• Part 3: PID namespaces
  • pidns_init_sleep.c: demonstrate PID namespaces
  • multi_pidns.c: create a series of child processes in nested PID namespaces
• Part 4: more on PID namespaces
  • ns_child_exec.c: create a child process that executes a shell command in new namespace(s)
  • simple_init.c: a simple init(1)-style program to be used as the init program in a PID namespace
  • orphan.c: demonstrate that a child becomes orphaned and is adopted by the init process when its parent exits
  • ns_run.c: join one or more namespaces using setns() and execute a command in those namespaces, possibly inside a child process; similar in concept to nsenter(1)
• Part 5: user namespaces
  • demo_userns.c: simple program to create a user namespace and display process credentials and capabilities
  • userns_child_exec.c: create a child process that executes a shell command in new namespace(s); similar to ns_child_exec.c, but with additional options for use with user namespaces
• Part 6: more on user namespaces
  • userns_setns_test.c: test the operation of setns() from two different user namespaces.
• Part 7: network namespaces
• Mount namespaces and shared subtrees
• Mount namespaces, mount propagation, and unbindable mounts
