Traefik + grafana help

Hi, I'm a junior MLE engineer who likes to play with containers and services quite a lot in his free time.

Anyhow, for my purposes I've built a small personal website service, and together with several others for fun, I've put Traefik reverse proxy before them.

Now, I would like to setup prometheus and grafana for some basic metrics (requests, memory, in future i'll try to play with bot detection etc).

My problem is, I've searched the Internets for some kind of a tutorial, and they all assume I am using Docker Swarm, which I don't (just a single Hetzner instance), or a k8s cluster, which I most definitely dont.

Is it really impossible to setup grafana for my simple setup?
Is there a tutorial out there I've missed? If there is, can you link it?
If there isn't, how can I modify the tutorials for my simple use case?

Thanks :D

Is datadog good for the long haul? ...or nah?

My org is currently looking to consolidate logs, metrics, and traces all into one vendor. We've POC'd a few that claim to do this, like new relic, dynatrace, and datadog, but frankly sometimes it seems like the POC is not representative of reality (I've heard some horror stories about doing exactly this in one of these three companies). At the moment we're leaning toward datadog.

We try to be a forward looking org and don't want to get fuckin stuck (again lol) on a tool that will just get less relevant a few years down the road (happened to use a handful of times)

So my main question is to those that use datadog, is it going to be as relevant to your org in a few years?

Today I blew up my self-hosted k8s cluster! Don't dist upgrade without thorough testing!!

I manage patching for large cloud environments. I should know better. Its basic operations procedure. Well, I decided to cut corners in my home lab and every k8s node (Ubuntu 2104) would boot into kernel panic) Without backups, it's impossible to tell what went wrong and where.

Lessons learned, take backups in your home labs!!

Advice on cloud based tools for A CICD pipeline.

Can I get some advice? I need to create a cloud-based CICD pipeline for a project. No one wants to touch it, so I'm stepping up to do it.

The task is to create a CICD pipeline in the cloud. Which cloud service is up to me, and it'll have to get approval from the team.

I am not sure what would be the best route to do so as I'm still learning Jenkins and TeamCity(on-premise), but I am not super great with them or cloud-based products. I'm having trouble with that; I'm not sure what is the best route to take.

I need to run checks on each pull request. To give context, each pull request contains an Angular app with the feature changes and a python automation suite that tests the app changes.

I need to start a local angular server, run the python tests (~3hr runs) on Windows chrome and Mac Safari, among other checks. CICD pipeline should be able to handle multiple PRs getting created at different times. Currently, we have two peak hours; for the sake of argument, they are 5 am and 5 pm.

The team would like to use Jenkins, but I'm not restricted to it. I have been looking at AWS EC2, AWS ECS, TeamCity Cloud, GitHub Actions, Azure. Anything with a Mac Agent and can parallelize builds even with Kubernetes. I am trying to account for cost as well.

What cloud-based CICD tool have you guys used and had success with? What is the best way to accomplish this?

Thanks in advance.

Automating port-forwarding for WSL2

I couldn't connect to my WSL2 local machine so I obtained the IP address inside of WSL2 by doing:

​

ip addr show eth0 | awk '$1 == "inet" {gsub(/\/.*$/, "", $2); print $2}'

​

And then followed up with:

​

netsh interface portproxy add v4tov4 listenport= listenaddress=0.0.0.0 connectport=2222 connectaddress=172.24.40.141

​

Is there a way to automate this process?

How do I implement Kubernetes in my current backend services?

Currently there's 1 database(ravendb) and 3 backend services running and 1 angular frontend app. Backend is in nodejs and I'm using pm2 to run all of them. I'm new to kube and don't know how it would benefit my currently running services. Can someone let me know how its gonna lay out the services before I learn kube? It would be very helpful

Adopting SRE Culture - Defining SLOs

When adopting the SRE culture and defining Service Level Objectives, remember that an SLO must be
• Achievable - being unrealistic would not work at all
• Relevant - corresponds to a critical user journey (CUJ) and reflects customer satisfaction
• Cost Effective - often ignored in order to achieve something impractical and unfeasible; connected to the "Achievable" characteristic
• Measurable - have a proper SLI metric, preferably time bound; metric should correlate with outages
• Having a bit realistic and relaxed threshold than SLA (say 99.99% availability SLO and 99.5% availability SLA), if SLA is defined - all services should have SLO, irrespective of whether SLA is defined

One more thing, there is no one-size-fits-all approach towards defining SLOs. A single SLO cannot be applied for every user journey.

Please do share your thoughts in the comments section. Any other characteristic you think can be added?

I wrote a library that simply generates English words and sentences



It does not involve testing frameworks and data model,So its application scenarios are more simple to use, does not consume too much memory, it supports custom lexicon and a variety of response formats, I am an open source novice have any suggestions and questions welcome PR.

What are your experiences with Mac Pro / Mac Mini hosting services?

There has been this thread 4 years ago that is still very educational, but AWS got into this game since then, was also able to found new players (e.g., macincloud), and the Apple also came out with their M1 chips as well.

A personal reason behind asking is that planning to get back into iOS development after years, and currently on a budget, but even if I ordered a Mac Mini M1 now, it wouldn't deliver until early September.

Create production grade Kubernetes clusters in Hetzner Cloud in a couple of minutes or less

Hi!

I just finished building a Ruby gem that allows you to create super cheap, production grade Kubernetes clusters in Hetzner Cloud very, very quickly. It uses k3s as K8s distribution because it's very lightweight, leaving more resources to workloads. I love it. The tool does everything to create a ready to use cluster in Hetzner, including the ability to provision load balancers and persistent volumes out of the box.

If you are looking for a very affordable way to easily create and manage self hosted Kubernetes clusters, and are happy with a European location (Germany or Finland), then check it out!

You can find the repo at https://github.com/vitobotta/hetzner-k3s

I would appreciate any feedback or suggestions on how to improve it in terms of functionality etc. Can you please give it a try if you already have an Hetzner Cloud account or are willing to create one?

Also if you have experience with k3s already and have suggestions about it, please let me know.

Thanks!

Application Server Migration on EC2

I hosted a java/j2ee web application in the cloud on ec2. It's just a lift and shift. I'd like to get rid of Web logic application server and replace it with Tomcat. Will there be any unforeseen issues? Any pointers? Thanks.

What is DevOps?

Every time a non-technical friend asks me what I do, I try to explain what the cloud is and how I work in the cloud in automation and architecture. Everybody always says “I have no idea what you’re talking about and I don’t know what you do”, despite me trying to explain it. How do you describe DevOps to your non-technical friends/family in laymen’s terms?

Fedora or Ubuntu

I'm a CS student wanting to get into and learn devops related topics like containers, etc., machine/deeplearning

I really don't know which one to use out of the two, just that I like Fedora's stock GNOME better than Ubuntu's version of GNOME. But from what I've read Fedora has better support for podman than docker. Is it a big trade off in my path to learn and explore more about the field mentioned above ?

Have some moderate experience of using linux from Ubuntu to arch with only window managers, but never settled on one distro

Really sorry if it's a noob question
Thanks in advance !!!

Gitea with Azure AD Authentication + Drone CI. It is a good start for my home lab!

Self-hosted options might be losing their place with cloud-native applications. But for your own experimentation, it is a great addition to complement your cloud lab environments. It's pretty straightforward and fun hosting your own Git, Azure AD, and CI

Today I finished my gitea installation, configured authentication with azuread, and started setting up drone ci.

What can I use to redirect http request coming to my public facing server to on premise webserver?

I have vpn server on linode that has ip 10.8.0.1 and it is always connected to its client 10.8.0.2 which is running apache webserver. Now for some reason I cannot directly make on premise apache webserver open to wan by port forwarding so I want to know if there is a way that if someone visits my website.com the tool refirects —-> 10.8.0.2 internal private ip.

Because both nodes are within same vpn there is nothing blocking any traffic.

Is traefik a possible tool to do that ?

Challenges working with AWS?

We are working on a platform that provide tools for developers to create their own custom, reusable component on AWS. We want to help developers to skip the not-so-interesting part of configuring their AWS and also teams who want to create, standardize how they can access their AWS environments.


Some of the problems that we see are that developers might not have the necessary skillset, or do not want to handle the complexity of spinning up their own infrastructure.

​

Because we are still working on finding out some of the challenges that they might face, would like to ask about some of the challenges that developers or you might face from your perspective.
