Is it ok to use the replication parameter with bitnami postgres?

const sequelize = new Sequelize('database', null, null, {
dialect: 'mysql',
port: 3306,
replication: {
read:
{ host: '8.8.8.8', username: 'read-1-username', password: process.env.READ_DB_1_PW },
{ host: '9.9.9.9', username: 'read-2-username', password: process.env.READ_DB_2_PW }
,
write: { host: '1.1.1.1', username: 'write-username', password: process.env.WRITEDBPW }
},
pool: { // If you want to override the options used for the read/write pool you can do so here
max: 20,
idle: 30000
},
})

https://sequelize.org/docs/v6/other-topics/read-replication/

The doc says that

I've read read replica are switched using round-robin, I am guessing it means that the load is distributed using round-robin, but what happens when the write server goes down, does one of the read replica becomes a write db? Secondly, does bitnami postgres helm chart works well with this read replica parameter, or you need to use another library in order to make it work? I am thinking the write db if it shuts down the whole application just crashes on the write side and that's also what bitnami assumes.

No operation guys in Devops anymore.

Have you guys noticed that operations/ app engineering part of DevOps is dissipating? Soon, there will be only developers.

When am I ready for a junior role?

I have been spending most of my free time over the last few months studying DevOps related things so that I can leave my Help Desk job. I have been using the roadmap(https://roadmap.sh/devops) to help guide my studying and now I'm wondering how far down the list I should get before I should think about applying? I know mastering all of it is ideal but in your experience, how much of this do you expect a junior devops candidate to know or have experience with?

OpenTelemetry Tracing - What are the options?

So OTel is all over the place, but many developers are still paying tons to their APM and they lean on logs and metrics w/o using tracing. But in microservices, you must understand the full context... services, APIs, dependencies, etc. Otherwise you are in a troubleshooting nightmare.

The thing is that OTel is "just" to instrument the data, you need other tools to create visualization and insights.

So Helios created this article that shares everything including the tools that can be used and examples on how to use them :

A resilient Redis cluster on kubernetes

I would like to share my experience of deploying a Redis cluster on Kubernetes with different Helm charts. While Bitnami is widely used for Redis clusters, I had doubts about its ability to handle production workloads following a chaos engineering test. After thorough research, I found an extremely robust Helm chart that operates without any problems. In this post, I will introduce this new Helm chart and detail the reasons why it's the superior choice for production deployments.

eliminating saas bills

Hey all, I'm getting sick of paying SaaS bills. Whenever we go with a vendor, it always feel a bit like signing a deal with the devil. The feature set is never quite as promised, the pricing is difficult to predict, we end up getting locked-in to that vendor as our codebases start reflecting that vendor's way of doing things specifically, and the load to switch to someone else becomes too high.

I'd much rather go with open-source solutions for most infrastructure/devops things but that's always met with:

1. We need to put in work to architect, deploy, and integrate the OSS solutions

2. We need to put in work to continuously update, upgrade, and support the OSS solutions

3. "How do we guarantee it's secure?"

To me, the first is a one-time cost we can easily put the work in to figure out. The second becomes negligible with the proper lifecycle automation (i.e. tie your infrastructure deployments to the rest of your deployment scheme). The third is silly, if you can secure your code, you can secure someone else's code, and popular open-source projects have many eyes looking at the security of the code. Not to mention...using SaaS for cicd/observability/identity/etc means trusting a third-party with ALL your proprietary code/data, how is that MORE secure?

I feel like I could easily put together a package of open-source solutions that deploys easily on k8s and solves 90% of the above issues. The last 10%, primarily involving bug-fixing/being a subject-matter expert when one of the tools inevitably breaks, could be reduced down to one or two people, or maybe even out-sourced.

Has anyone found success in replacing ALL their SaaS vendors with open-source solutions and fully self-hosting/supporting?

help with my job title.

How can you name a specialist DevOps/cloud architect?
I know this is a silly question, but at this point i don't know who am I anymore. And my colleagues don't know too.

I was hired as DevOps, but now I am in charge of all AWS infrastructure too. I am doing everything: CI/CD, runners, K8s, serverless apps together with trams, governance in AWS, monitoring. You name it.
I am doing AWS Cloud solution architect cert now.

How important are CSP certificates in today’s job market? (Q2, 2023)

Just for context;
BEng in Computer Engineering, MSc in Digital Networking, 8YOE in total, with 5 as a backend SWE.
Worked at startups most of my career, that never seemed to have DevOps engineers. So backend engineers typically handled the servers and infrastructure as part of our role.

I’m hoping to move purely into Cloud DevOps, and I’m wondering how important these certifications are to land a job.

My question: If I have 4hrs a day for the next 6 weeks, would you advise me to complete the popular DevOps roadmap?
Or study and try for at least 1 AWS cert?

(I can’t find the link to the roadmap, but you probably know which one I’m on about… it’s been shared 50000 times)

I honestly don’t have more time than this right now, with 2 little kiddos (one infant 🥲). I’m on a time crunch to get a job as one income is no longer sustainable with the new addition, just looking for some guidance so I don’t run in circles forever.

I am currently not working, took a year off for medical reasons.
Advice greatly appreciated from anyone and everyone 🙏


Edit: The cert I would attempt to take would be Developer Associate, since it’s closest to what I’ve been doing.

Pulumi Self-Managed vs Pulumi Cloud

I’m looking at migrating to self managed using s3 to store state and I’m finding that there aren’t a lot of resources or best practices. I was hoping to get some peoples experience in the types of challenges they have faced managing their own Pulumi backend, and the types of solutions you may have found useful.

For example, some big considerations seem to be concurrency, state locking, security, saving additional data such as history, backups.

Also, more of a specific technical question here but, when migrating code I’ve noticed that I need to use aws.lambda.Function and aws.lambda.CallbackFunction creates serialization errors. It only does this with s3 and not in Pulumi cloud. If anyone knows more details on how the backend choice affects serialization, that would be a huge help.

Thanks for any experiences/opinions!

How do you keep timezone data up-to-date?

Sometimes business requirements require converting from UTC to a specific timezone in the backend side for whatever reason.

Typically you would install tzdata in the Dockerfile, which has all the timezone information you need.

However sometimes timezone data changes (e.g. some country drops DST), causing potential issues in your code.

The fix would be to rebuild your containers, but this is a reactive solution. I’m looking for a proactive solution, other than constantly rebuilding your images. Preferably without even restarting your Pods (we’re assuming Kubernetes here)

So far I came across k8tz, which could be a solution.

How would you solve this issue?

Have you heard of DevOps, DataOps, DevTestOps, or AIOps?

These are just a few examples of the "Ops" that we encounter in our routine lives. As technology continues to evolve at a rapid pace, businesses are constantly exploring new ways to streamline their operations and optimize their workflows.

So what are your thoughts on the world of "Ops"? Have you encountered any other "Ops" that you find particularly interesting or valuable?

If this is true, then this is ridiculous. I would hate to be laid-off because the engineering team does not know how to manage the cost of observability.

Multi service ci/cd best practices

I want to understand what are the best practices for ci/cd for a multiservice app,
For example:
If I have a simple web server for displaying different system diagnostics for another project.
On each page of the server they will be info from a different containerised microservice which will be sent via api.

So what is the best practices for the pipeline of such an app?
Should every microservice be on a different repo which would have a seperate ci/cd pipeline?
Or should they be on the same repo with one pipeline?

Help will be much appreciated!

Thanks

Should I use Custom OS image or Docker or Ansible to manage config/installed packages?

I'm trying to have a fully automated pipeline to deploy out different lab VMs for myself.

For example

\- Deploy a fully configured Debian VM running Hashicorp Vault / Nextcloud / NGinx

I already have working Terraform pipelines hooked up to Github repos. It deploys out the Infrastructure.

But I can't figure out the best way to automate the next few steps

\- Install packages and pre-requisites

\- Configure software, install SSL certs

\- Push my private API keys into the VMs and pull newer secrets back to vault etc

Any advice is appreciated. Or if anyone has similar public Repos I can review
