So, I'm trying to get Nexus running based off of this image in Kubernetes, but it's failing with:. From the documentation it says that the process runs with UID and the volume must be mounted with those permissions:.

I've tried to search through the documentation to find a way to mount the volume with those permissions, however, I couldn't find any way to do it. If so, how? So, you can set the UID by InitContainerwhich launches before the main container, just add it to the containers path of the Deployment :. Here comes another workaround for this topic. As you can see, the directory belongs to root:nexus, and you can also check the files in the directory:.

Regarding Torsten Bronger 's commentwhen you configure ConfigMaps and Secrets in the volumes array in the pod spec, you can specify the permissions to allow the access you want using the defaultMode property, so while you can't set group and user ownership, you can allow processes in the pod to read files in those mounts.

Writing to a secret or config map does not really make sense and the default permission mode is anyway so reading shouldn't be an issue for any user. Sign up to join this community. The best answers are voted up and rise to the top.

I suspect this is due to having installed Docker via snapwhich I did as a way to install Docker version: docker versiondocker info preferred. There has been a reported issue on this here: You can install Docker using apt and it should work without any issue.

Let me know if it doesn't work.

I wish they put that on their snap page. Regardless, it doesn't really matter if it's maintained for my current purposes. I just wanted to get the older version installed on Ubuntu I tried with your Docker install script and it failed. I didn't try with apt. I'll see if it's any different.

Full kube-controller-manager. Controller manager may not assume it has root. Or should clarify if an additional mount is now required.

May have been introduced in cc sttts. Need to understand the expectations around these certs multiple pods, restarts, etc. Can we get folks to write a note to cover this problem in known issues? I've added an emptyDir mount to address that crashloop, which seems to work preliminary example. I don't think adding a writeable directory requirement just for a self-signed cert is a very good idea. It's up to the SIG if this is a 1.

I'm inclined to think the latter. I would prefer to avoid my current workaround of giving it a writeable location so those all sound fine to me. I could mint actual certs, mount from a secret, update clients. If there's merit. Like, how big of a deal is it that this is now always enabled vs before? I'll probably read through the various diffs after vacation. If this is going to get some text in release notes Known Issues seems like it shouldsomebody needs to draft the text and make a suggestion of it in ASAP.

Self signing in memory means you get a different cert each time it starts. It's probably better than nothing but it's not how things are supposed to work it's too inconvenient to manually verify the cert out of band in places users should trust it.

OTOH if you want to do that, maybe you'll provide a writable directory in the first place, or even a real cert. So I guess in-memory is probably OK. If folks inadvisably run apiserver and controller manager on the same system, they should at least not both try to use certs from the same place, or worse, write them there.

I'd expect something to be failing since random certs are generated each time the pod restarts, but don't see any impact implying this isn't yet improving security.

The auto generated certs are self signed, right? If so, and callers won't be able to validate the signer, which SANs they have don't really matter.

Yeah, they're self-signed. So looks like the 1. Main reason I was interested in the SAN is to get some clue about how a client would be expected to access these controller-manager pods for contrast, apiserver SAN has DNS:kubernetes and an internal record that always resolves to a kube-apiserve pod.

There are some other setups where even this wouldn't help. I think this is not a good solution. I got some issue regarding this, but none gave the root cause and solution. I saw you got the same problem in issue. But I got another issue because of this added securityContext. I see that it's possible to set securityContext via values.

The config he pasted goes in your "prometheus" object. I don't know where the helm chart puts that, but you should have one, as that's the resource that the operator uses to create your prometheus instance. You may need to adjust the name of the volume mount. Skip to content.

I can not understand why should set a securityContext. What is the root cause? This isn't required, for the last 5 months. Are you having the same issue?

Line 72 in cc64fb0. Am convinced now this is because the process runs by default with umaskand so gets set as instead. That works too, and might be better than fiddling with umask since umask is process wide afaik! I'll amend the patch later today. I'm seeing the same issue running minikube version: v0.

This, in turn, is using the default storage provisioner k8s. I suspect I've bumped into the same issue seen by yuvipanda. The Docker image used by the Redis Helm chart launches the Redis daemon as uid During its initialisation the pod encounters permission errors while attempting to create files on a persistent volume.

The Redis pod uses a persistent volume that ultimately maps to a directory on the minikube VM that is created with permissions owned by root :. If I chmod pvc-8fdd-e04de7-ba7cc9 the Redis pod will startup properly. If its safe enough this seems like a reasonable path of least resistance. Allowing some customisation of mountOptions in creating a persistentVolume in minikube could help i. The issue is that the volume provisioner isn't really responsible for the mounted volume's permissions, kubelet is.

This same problem exists basically for all externalVolume provisioners that don't have a mounter implementation in core. Local volumes I think are the only supported volume type that's got a provisioner outside of core, but has a mounter implemented in core. I don't know what the best option is, but it seems that if local volumes get better support, then perhaps minikube should switch to using the local volume provisioner instead of the hostpath-provisioner, and then that may resolve most of these issues.

Yup, thank you chancez.

I think being able to set those values will help in many cases. Issues go stale after 90d of inactivity. Stale issues rot after an additional 30d of inactivity and eventually close.

On my system Fedora 21I'm now unable to successfully build master. It looks like this comes from Could someone please take a look? ArtfulCoder vmarmol FYI. Do a make clean and try again. This usually solves it for me since the configuration is stale. Let us know how that works.

Here are the golang rpms I have:. I can replicate this locally, will get a fix. In the meantime, the workaround for a single binary is to use straight-up cgo: godep go build github.

I think the issue is that these scripts were not meant to be called in this way. This fails today because we started appending "cgo" to those paths. It succeeds when run inside the Docker build container though:. Would one of the two workarounds work for your usecase? I'm guessing you're trying to get a one-off binary for testing? So this definitely hinders my typical workflow. That said, if there's a better way to get the same results i.

I can switch. I had to manually install cgo which was also a pain to do for some reason dealing with permissions. I think the. Reply to this email directly or view it on GitHub: comment.

The fix that worked for some of us for the permission denied errors is in I guess we can surface that suggestion when we hit the error and continue from there.
