But in many Kubernetes clusters, it's likely that an attacker could exploit this issue. Installation of this patch will likely require a reboot of the host to be effective. Thanks been battling all day , permissions , running the container in windows terminal then stopping it and running it in WSL2 fixed the issue for me.

A work-around is to use other builder strategy, like Kaniko or Spectrum, with kamel install --build-publish-strategy=kaniko or by editing your IntegrationPlatform directly. At this point, it's important to note that when Docker (or other CRIs) are used in a Kubernetes cluster, the seccomp filter is disabled by default, so this vulnerability could be exploited in those cases. Finally, And then I went through the procedure with and I still don't know which one helps me to create the integration.

The text was updated successfully, but these errors were encountered: New issues are no longer accepted in this repository. Some context can be found in containers/buildah#1901. Cheers! In effect, the profile is a allowlist which denies access to system calls by Can a VGA monitor be connected to parallel port? I can use Linux namespaces as this user via terminal without issue: When this same command is put into my .gitlab-ci.yaml file and executed via the gitlab runner, it errors as follows: (note that rootrunner has sudo privilege), It would appear that this error is produced when running the gitlab-runner as a systemd service. The base Docker image contains an SSSD setup that binds to our AD so users run their jobs with their own credentials.
