Hmm I want to "upgrade" my home #k8s cluster to either #Fedora #CoreOS or #RHCOS, and drop docker in favour of cri-o, but I'm not sure what they best way would be to go about it without too much down time. I'm not sure if you can mix container runtimes in #kubernetes?
Could just rebuild one host at a time if they can be mixed.

#introduction Hello! I'm Hamzah. I'm a #linux/#devops engineer in my day job. I live in #london.
I consider myself a hardcore geek, but these days most of my time is taken up by my three kids and wife.

I'm very interested in automation, and have a small addiction to #ansible, #kubernetes and #HomeAssistant.

Has anyone deployed #bitwarden on #kubernetes? I'm going to give it a shot over the weekend.

Does anyone here run #gitlab in #kubernetes?
I'm interested in moving my Omnibus gitlab instance to my #k8s cluster, but I'm a bit confused about how it all interacts to be honest.

Has anyone run a #K8S cluster across DCs? I'm reading everywhere saying it's not a good idea
What is the current state of #kubernetes cluster federation? Last time I looked into it, it was in very early stages.

This might be a very obvious question.... but when running #nginx on #k8s, what should worker_processes be set to? As far as I can tell from googling, nginx isn't cgroup aware, so auto wouldn't work. #kubernetes #devops #sysadmin

Hmm using #Traefik as my ingress can be a bit annoying at times as it uses IngressRoute object instead of the normal #kubernetes Ingress objects. It means things such as the Jaeger Tracing operator can't create Ingress rules automatically

I just discovered helmfile. I love it already! #kubernetes #k8s

It's so frustrating that #kubernetes tries to do a chown recursively every time a pod starts up if you have fsGroup set. For a volume with a very large amount of files (eg minio!), it means the pod will take ages to start up.

Finally got my #kubernetes cluster back up. All I wanted to do was upgrade kubernetes, and add a few nodes with Fedora CoreOS, but it exploded in my face. Switched back to CentOS 7 for now.

I bought 4 more nodes for my #kubernetes #homelab cluster.... my wife is going to kill me when she finds out 😅

Going to try and upgrade my #kubernetes ingress from #Traefik v1.x to v2.x.

I've been spending the last week going through a #RedHat training course for #OpenShift. I really want to switch my home #kubernetes cluster from K8S to OpenShift, but it would be problematic as I have very little RAM and CPU for my cluster.

It totals 16GB, and 4 CPU cores across two nodes, and the CPUs aren't great either (G1840T).

I want a couple of quad core i7/i5 NUCs to add to the cluster. If I come across some for a reasonable price, I will definitely be getting them.

I wish FreeIPA had better integration with other tools, such as it would be so nice if #traefik or #cert-manager could request certificates from #FreeIPA (ie Dogtag), or if #kubernetes ExternalDNS could setup DNS records on FreeIPA's DNS server (BIND).

I've just upgraded the last of my "standalone" docker #traefik instances to v2. I'm a little nervous to do it on my #kubernetes as I'm sure it will break a lot of things :(

I set a horizontal pod autoscaler on my #mastodon sidekiq deployment in my #kubernetes cluster. It's cool seeing the number of pods increase. #mastoadmin

Just wiped my two HP Microservers to add them to my home #kubernetes cluster. I used #RHEL7 Atomic Host. It's a shame #Fedora CoreOS isn't stable yet, and isn't compatible with #kubespray yet.

This is cool https://blog.kontena.io/kontena-lens-desktop-app/ #kubernetes #k8s

Hmm really need more nodes for my home #kubernetes cluster. I tried to deploy the #elasticsearch Helm chart, but it was pretty much unusable, mainly because my nodes are formed of very crappy Intel Celeron CPUs which are already over worked.

Upgrading my #kubernetes cluster.... I hope this doesn't go badly
