lxc-start-ephemeral: start an ephemeral copy of an existing container

NAME

lxc-start-ephemeral - start an ephemeral copy of an existing container

SYNOPSIS

lxc-start-ephemeral [-o] [-n] [-d] [--bdir] [--user] [--key] [--storage-type] [--union-type] [--keep-data] [COMMAND]

DESCRIPTION

lxc-start-ephemeral start an ephemeral copy of an existing container.

OPTIONS

-o

Original container name

[-n]

Name of the ephemeral container (defaults to a random suffix).

[-d]

Start the container in background and print the name and IP. This option can't be used if a command is passed.

[--bdir]

Directory to bind mount into container. Can be passed multiple times.

[--user]

The user to connect to the container as. Used when passing a command to lxc-start-ephemeral.

[--key]

Copy the provided SSH public key into the container.

[--storage-type]

Specify the type of storage used by the container. Valid types are tmpfs or dir.

[--union-type]

Force a specific union file system. Can be one of: overlayfs aufs

[--keep-data]

Use a persistent backend instead of tmpfs. With this option, you can lxc-stop and lxc-start the no longer so ephemeral container (it's still an overlay, but a persistent one).

[COMMAND]

Immediately run the provided command in the container. This uses attach if the kernel supports it, otherwise uses ssh. This is incompatible with daemon mode.

EXAMPLES

lxc-start-ephemeral -o p1

Simply start an ephemeral container and attach to the console. This container will be based on existing container "p1".

lxc-start-ephemeral -o p1 -n p1-ephemeral -d

Start an ephemeral container based on p1 called p1-ephemeral and print its IP and name to the console instead of attaching.
