Create symlink in stopped container instance

Incus
1

Some time ago, I asked how I could create a symlink in a stopped container and the method at the time was to use curl:

curl --unix-socket /var/lib/lxd/unix.socket -s lxd/1.0/containers/mycontainer/files?path=/etc/runlevels/default/firstboot -H "X-LXD-type: symlink" -H "Content-Type: text/plain" -d "/etc/init.d/firstboot"

What’s the Incus equivalent to this command ?

Hi!

See here the full REST API for Incus.

First, to check if everything works with curl, use the following. The output is similar to incus info.

curl --unix-socket /var/lib/incus/unix.socket incus/1.0 | jq .

You want to create a symbolic link in a container. Use this.

$ curl --silent --unix-socket /var/lib/incus/unix.socket incus/1.0/instances/mycontainer/files?path=/symlink_path -H "X-INCUS-type: symlink" -H "Content-Type: text/plain" -d "/etc/passwd"
{"type":"sync","status":"Success","status_code":200,"operation":"","error_code":0,"error":"","metadata":{}}
$

In summary, from
lxd/1.0/containers/mycontainer/files?, replace with
incus/1.0/instances/mycontainer/files?

That is,

  1. Use incus.
  2. Use instances instead of containers.

Note that an instance is the name of either a container, a virtual machine, or an application container (i.e. Docker). The API is cleaner when it says instances.
