Do you have some kind of "migration guide", how to move from varlink

Currently we connect over ssh, and then run this command:

sudo varlink -A "podman varlink $VARLINK_ADDRESS" bridge

The complete command goes into the PODMAN_VARLINK_BRIDGE, with ssh etc.


What environment variable should be exported now, and how should it be
set up ?

Do we just export the same variables as before, or are there some new
ones to use:

export PODMAN_USER="root"
export PODMAN_HOST="127.0.0.1"
export PODMAN_PORT="36230"
export
PODMAN_IDENTITY_FILE="/home/anders/.local/machine/machines/box/id_rsa"
export PODMAN_IGNORE_HOSTS="true"

Eventually found out (in the source), that the new variable is called
$CONTAINER_HOST and that it follows the same syntax as $DOCKER_HOST :

CONTAINER_HOST=ssh://root@127.0.0.1:36230
CONTAINER_SSHKEY="/home/anders/.local/machine/machines/box/id_rsa"

Can we still use "sudo", or do we have to enable ssh logins for the
root user now ?

Currently root login is disabled (default), since we found the sudo
varlink workaround.


Tried to use the varlink resolver and the varlink socket, and it
worked - for a while.

$ sudo varlink resolve io.podman
unix:/run/podman/io.podman;mode=0600

But we never got interactive (-it) sessions working, so not using
those anymore...

It seems like the user will either be root, or have the equivalent
access to the podman socket (through the user or group or something)

Running "sudo" doesn't really work anymore, since it is now just
a path (/run/podman/podman.sock) and not a command (varlink).

This would be for existing "podman-machine env" and "minikube podman-env."

Both of those are currently using the varlink bridge, and podman
version 1.8.2

It seems like most of the bugs with version 1.9.2 have now been fixed...
So should be able to use 2.0 (RC), while support clients 1.6 and up.

Probably will stick with 1.9.3 and varlink for the upcoming releases,
since those are only a couple of weeks away (and already implemented).

Sounds good to me.  Podman 2.0 is not released anywhere yet.  Just in Beta.
