That's where we were three years ago, and went down the road of running our own cluster (we chose okd). It works, but it is a lot of work.. especially if you start opening it up to users. I haven't yet regretted putting our internal apps into it, everything's been solid.

Kubernetes is the only viable choice imo. Its easier today than it used to be by a significant margin with kubeadm being GA for bootstrapping your cluster. It's still a fair amount of work and you need to still do a lot yourself, you can't easily defer the loadbalancing problem to aws but instead need to build your own contraption. I wouldn't build a full kubernetes deal just for one app though, there are easier ways of getting what you want regarding load balancing: you'd need to solve the load balancing problem in addition to all the kubernetes problems.

Two performance tips I have for nginx ingress; First is to make sure the service load balancer that fronts the nginx pods is set to External traffic policy local and then that you the load balancer policy is set to ewma. This is a contrived example; but I have 3 handling 4K-10k rps between them, using half a cpu each. Receiving 40 MBs. freeasinbeer fucked around with this message at 05:19 on Oct 17, 2020 |

These are good suggestions. I'll try them out next week. In my case I'm going to need to be able to handle upwards of 60k to 100k rps, probably worth 4-7 gbps. I'm still leaning now towards trying out the alb ingress controller since there has been so many people name dropping it. https://kubernetes-sigs.github.io/aws-alb-ingress-controller/guide/controller/how-it-works/ Looking at the architecture diagram alone its delightfully simple and eliminates a whole userland packet processing, and an entire node hop if this controller is intelligent to only have nodeports registered of nodes that actually contain a particular pod rather than yoloing it out and letting iptables deal with it if necessary. Your post is a bit hard to read, but for everybody else's reading pleasure, this is what is being referred to for tuning nginx https://kubernetes.io/docs/concepts/services-networking/service/#aws-nlb-support quote:Unlike Classic Elastic Load Balancers, Network Load Balancers (NLBs) forward the client's IP address through to the node. If a Service's .spec.externalTrafficPolicy is set to Cluster, the client's IP address is not propagated to the end Pods. https://github.com/kubernetes/ingre...md#load-balance quote:Sets the algorithm to use for load balancing.

Hadlock posted:Nuke your etcd cluster and get back to me At least if you're going to do it, do it with a private cloud setup. Company I worked for had a few tens of thousands of servers in DCs around the world that were either being migrated or their foot print was being migrated to private cloud to then have groups run k8s on top of.

I interviewed at a place a few months ago that wanted a single engineer to run the k8s on prem cluster running on hyper v in a managed colo somewhere. Most of the interview was spent just trying to understand why.

If you're not running Kubernetes at scale, and you have a basic understanding of distributed systems/schedulers and PKI, the operational overhead of K8s is totally overstated. Sure, trying to troubleshoot a non-functioning etcd is a pain in the rear end, but you can also just throw out your cluster and restore the whole thing from Velero in ten minutes. I'd still prefer a cloud-managed cluster instance any day, but if I was in some airgapped environment that had to be on-prem because of somebody's reasons, I don't think there's reason to be scared of it or choose a worse approach for managing your applications.

So Bitbucket is shuttering their self hosted option for some reason and we need to migrate to a new self hosted source control system. Gitlab is the obvious choice but I was curious is anyone uses anything else to success? Just want to weight our options

Yeah Atlassian is forcing everyone to move to the cloud version of their poo poo unless you are willing to pay $Texas for an indulgence. It’s pretty cool  We run GitLab for about 1000 users and are happy with it. Unless it’s for one small team I recommend springing for one of the paid tiers. The free edition is pretty crippled, missing poo poo like mandatory approvals before merging a pull request and “a working search feature”. You need at least the starter tier to get back near feature parity with Bitbucket.

Gitlab is the obvious choice but I was curious is anyone uses anything else to success? Just want to weight our options We're using Gitlab and are quite happy with it as well. Sometimes it's got minor bugs that have been left open for 2+ years in favor of adding more enterprise paid features, which I can't really blame them for. None of those have been show-stoppers, just stuff like the build cache not triggering and slowing down builds by a few minutes. I might consider Gitea if I did not need a built-in CI/CD system or built-in package manager, and/or if I didn't have a beefy server to host it on. Gitlab is a massive resource hog, while Gitea runs on a Pi and feels blazing fast at all times. Then again, Gitlab is an enterprise product with all that it entails, e.g. I've never had a single issue running a plain `gitlab backup create && apt-get upgrade` after a new release; whereas Gitea is an open-source project that isn't even dogfooding itself yet (is code hosted on Github). edit: Gitea apparently supports git mirroring (while it's a paid feature in Gitlab) so you can maybe install both with mirrored repos and get a feel for which one you like better.

GitHub as an on-prem offering as well, GitHub Enterprise Server. The latest version even supports GitHub Actions, so you've got some CI/CD builtin (though we haven't upgraded to that version yet so I don't have any experience with it yet).

I want to create a small webapp for friends & family to use during meetups. Most of the time it will just serve some static content, but once in a while it will need to fire up an external process (a docker container) that could really benefit from some compute oomph. This is more of a hobby fun project to learn a different webdev stack than something we actually need, so I'd like to run it for free or for literal peanuts. It looks like I should be able host it all on the Google Cloud free tier. Dockerized webapp in the App Engine (28 hours/day), then upon demand run the compute jobs using Cloud Run (180k vCPU seconds / month), store generated data in Cloud Storage (5GB). I've looked at AWS, Azure, DO, and Heroku and their (permanent) free tiers don't seem to compare. Is there any pitfall I should be aware of?

If it's mostly static content then just throw it in a storage bucket to avoid the web server running at all, and use Cloud Run to initiate the occasional compute. Only pitfall I can think of is to make sure you use a robots.txt to ensure your static site isn't crawled as it will consume bandwidth you don't need. And maybe set up a Budget Alert so you're aware if you start to approach the free tier threshold.
