# in environment ?
by lejeczek
Hi guys.
Do you use # in your envs?
I wonder if it's just me having issues with those.
For a test, to reproduce the issue, 'ghost' web solution
would be easy & quick:
-> $ podman run -dt ...................... --env
database__client=mysql --env
database__connection__host=11.1.0.1 --env
database__connection__user=ghostadm --env
database__connection__password='xyz#admghost' --env
database__connection__database=ghost_xyz --env
url=https://ghost.xyz
So far all I've tried with 'database__connection__password'
failed, quoting &| escaping.
I often use # - does anybody have a way to make it work?
many thanks, L.

RunRoot & mistaken IDs
by lejeczek
Hi guys.
I experience this:
-> $ podman images
WARN[0000] RunRoot is pointing to a path
(/run/user/1007/containers) which is not writable. Most
likely podman will fail.
Error: creating events dirs: mkdir /run/user/1007:
permission denied
-> $ id
uid=2001(podmania) gid=2001(podmania) groups=2001(podmania)
context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
I think it might have something to do with the fact that I
changed UID for the user, but why would this be?
How troubleshoot & fix it, ideally without system reboot?
many thanks, L.

shouldn't the current directory be the default context for "podman build"?
by Robert P. J. Day
"man podman-build" suggests that the context argument is optional:
SYNOPSIS
podman build [options] [context]
podman image build [options] [context]
...
If no context directory is specified, then Podman will assume
the current working directory as the build context, which
should contain the Containerfile.
but if i have a directory with nothing but a Containerfile, i get:
$ podman build
Error: no context directory specified, and no containerfile specified
$
OTOH, specifying context of current directory:
$ podman build .
STEP 1: FROM alpine:latest
... etc etc ...
thoughts?

ro sysfs doesn't affect spc_t?
by Peter Hunt
Hey team,
I've got some odd behavior on a podman in Openshift use case I am trying to
figure out. I am trying to run podman in openshift without privilege, extra
capabilities and ideally a custom SELinux label that isn't `spc_t`. I have
managed to adapt the `container_engine_t` type to get past any denials, but
now I'm hitting an issue where the sysfs of the container is read only:
I am running with this yaml:
```
apiVersion: v1
kind: Pod
metadata:
name: no-priv
annotations:
io.kubernetes.cri-o.Devices: "/dev/fuse"
spec:
containers:
- name: no-priv-rootful
image: quay.io/podman/stable
args:
- sleep
- "1000000"
securityContext:
runAsUser: 1000
seLinuxOptions:
type: "container_engine_t"
```
and using a container-selinux based on
https://github.com/haircommander/container-selinux/tree/engine_t-improvem...
when I run this container, and then run podman inside, I get this error:
```
$ oc exec -ti pod/no-priv-rootful -- bash
[podman@no-priv-rootful /]$ podman run ubi8 ls
WARN[0005] Path "/run/secrets/etc-pki-entitlement" from
"/etc/containers/mounts.conf" doesn't exist, skipping
Error: crun: set propagation for `sys`: Permission denied: OCI permission
denied
```
What I find odd, and what is the subject of this email, is that when I
adapt the selinux label to be "spc_t":
```
type: "spc_t"
```
the container runs fine. There are no denials in AVC when I run
`container_engine_t`, but clearly something is different. Can anyone help
me identify what is happening?
Thanks
Peter

lsetxattr with GlusterFS ?
by lejeczek
Hi guys
I'm trying to run a container with some vols on a GlusterFS
volume:
-> $ { export _NAME="ko.xyz"; export
_PATH=/00-APKI//${_NAME}; echo; mkdir -p
${_PATH}/{,root,media,files,apps,themes,images,settings,data,public};
}; podman run -dt --restart=always --volume
${_PATH}/config.production.json:/var/lib/ghost/config.production.json
--volume ${_PATH}/root:/root:z
Error: lsetxattr /00-APKI/ko.xyz/media: operation not supported
..
GF vol is:
Volume Name: APKI

_autofs_ makes the moutpoing with:

10.1.1.100,10.1.1.99,10.1.1.101:/APKI
I fiddled with both autofs & gluster but cannot figure it
out - would somebody know what's wrong/missing here?
I suspect it's due to SE labeling - which would be great to
have, naturally.
many thanks, L.

subuids in sync across ?
by lejeczek
Hi guys.
I thought this must be trivial & common yet I failed to find
here on the list & the net, any info on:
how to keep subuid & subgid in sync across different PCssystems?
Would it be simply a matter of keeping all relevant /etc
bits in sync - naturally I'm thinking all the bits which are
important to _podman_
many thanks, L.

docker registry token authentication and podman
by Михаил Иванов
Hallo, not sure if this is the right place for such question, but still.
I'm trying to set up a token authentication for docker registry and using
podman login to test it. As per description podman should receive
'401 Unauthorized' error and headers in the reply should contain
'Www-Authenticate:' entry. As far as I understand, podman should then
automatically try to access url, specified in this entry to get the token.
But it just terminates with 401 error. I verified registry access with curl
and I see, that Www-Authenticate is present.
Should podman actually request the token automatically or do I misunderstand this?
Best regards,
