DevOps course but text based, not video?

I'm in search of a DevOps roadmap course, but text based. I'm not good at following video based tutorials. Any recommendations?

DevOps Best Practices 2021

To get the most out of any technology, it is important to inculcate or adopt the best practices, as they not only guarantee seamless workflow but also ensure efficient time management, avoid redundancy, save efforts and cost, among other things. Similarly, organizations need to use certain practices and techniques while implementing various DevOps concepts and processes to innovate faster, ensure consistency, and streamlining successful application/software development and infrastructure management. These best practices include:

1. CI/CD
2. Microservice.
3. Monitoring and Logging
4. Infrastructure as Code
5. Shift Left

Terraform: remote-exec error ssh failed

I have no idea why I keep getting this error, the key is obviously where it's supposed to be.

Error: remote-exec provisioner error

│

│ with aws_instance.devops,

│ on main.tf line 87, in resource "aws_instance" "devops":

│ 87: provisioner "remote-exec" {

│

│ Failed to read ssh private key: no key found

​

The key is located in the same folder from where I run terraform apply.

​

Here's a relevant part of the script (within aws_instance resource)

​

provisioner "remote-exec" {

inline = [

"echo 'SSH IS READY'"

\]

}

connection {

type = "ssh"

host = self.public_ip

user = "ubuntu"

private_key = file("devops.pem")

}

On-call by default: how we do it at incident.io

https://incident.io/blog/on-call-at-incident-io

Hey all!

My colleague Chris (https://twitter.com/evnsio) wrote a great guide to on-call that we've shared as a blog post.

It's a lot of good common sense, but explained in plain language and might be a good starting point for anyone setting up an on-call rota at their own companies.

Hope you find it useful!

What does a Cloud Security Engineer actually do?

On one hand, I hear people say Cloud Sec roles are mostly just IAM engineering and management.


While on the other hand, I hear it's a lot of automation of monitoring tools and compliance frameworks.


I'm sure it's both but what could I reasonably expect if I were to walk into a cloud sec job tomorrow?

I'm new in DevOps, Question for Ansible + git + AWS

Hi everyone, I’ve started working from SysAdmin to DevOps, I have a task, use Ansible to automate the deploy from git.

Currently to perform an deploy I perform these steps:

git describe
git status
# Deploy new version
git fetch --tags
git reset --hard <target_version>


Is it possible to automate the deploy of new versions through Ansible? and in case the task fails to return to a previous version?

Regards,

Confused about Devops transition

I have been learning devops related technologies from a while. But whenever I go through blind, most of people say SRE/Devops are not much required. They are someone who failed SWE interview. Google needed just support engineers so they names it SRE to look cool.
Especially developers saying, SWE is always a best job and they have to look after Devops related task too

Also on the other side of internet Devops people are getting paid more than SWE sometimes ( for good skills).

I don't understand why these people downgrade Devops/SRE jobs.

So according to you, what skillset a successful devops engineer must have?

How to become a good DevOps Engineer? Newbie here, I need advice

I need advice from experienced DevOps engineers. I am new in this field and sometimes it's hard to keep up with all the tools, I guess I am having a hard time integrating all the things I've learned so far and continuously learning more.

I have experience as a backend web developer and I transitioned into this role, I'm an intern and I need advice. I enjoy what I do but sometimes I feel a bit lost, tbh.

Is Terraform is the only choice in 2021/2?

I've been looking at Terraform and know it's very powerful and mainstream.

My only issues:

* HCL language is an interesting DSL, but would prefer just using a mainstream language, but I know CDKTF exists but this seems very young at the moment?
* Terraform state, this deeply troubles me, I think HashiCorp has made a major architecture flaw, a permanent state shouldn't be ever needed in theory at least, however having ephemeral state that can be re-generated would be a good optimisation.

What alternatives are there that is:

* Free open source
* Doesn't use state
* Uses mainstream language and no custom DSL
