Troubleshooting
A list of common issues and solutions for Podman
1) Variety of issues - Validate Version
A large number of issues reported against Podman are often found to already be fixed
in more current versions of the project. Before reporting an issue, please verify the
version you are running with podman version
and compare it to the lastest release
documented on the top of Podman's README.md.
If they differ, please update your version of PODMAN to the latest possible and retry your command before reporting the issue.
2) No such image or Bare keys cannot contain ':'
When doing a podman pull
or podman build
command and a "common" image can not be pulled,
it is likely that the /etc/containers/registries.conf
file is either not installed or possibly
misconfigured.
Symptom
$ sudo podman build -f Dockerfile
STEP 1: FROM alpine
error building: error creating build container: no such image "alpine" in registry: image not known
or
$ sudo podman pull fedora
error pulling image "fedora": unable to pull fedora: error getting default registries to try: Near line 9 (last key parsed ''): Bare keys cannot contain ':'.
Solution
- Verify that the
/etc/containers/registries.conf
file exists. If not, verify that the skopeo-containers package is installed. - Verify that the entries in the
[registries.search]
section of the /etc/containers/registries.conf file are valid and reachable.- i.e.
registries = ['registry.fedoraproject.org', 'quay.io', 'registry.access.redhat.com']
- i.e.
3) http: server gave HTTP response to HTTPS client
When doing a Podman command such as build
, commit
, pull
, or push
to a registry,
tls verification is turned on by default. If authentication is not used with
those commands, this error can occur.
Symptom
$ sudo podman push alpine docker://localhost:5000/myalpine:latest
Getting image source signatures
Get https://localhost:5000/v2/: http: server gave HTTP response to HTTPS client
Solution
By default tls verification is turned on when communicating to registries from
Podman. If the registry does not require authentication the Podman commands
such as build
, commit
, pull
and push
will fail unless tls verification is turned
off using the --tls-verify
option. NOTE: It is not at all recommended to
communicate with a registry and not use tls verification.
- Turn off tls verification by passing false to the tls-verification option.
- I.e.
podman push --tls-verify=false alpine docker://localhost:5000/myalpine:latest
