Should I go Vendor Focus(AWS/Azure/GCP) Route or Cloud Native Route?

Rookie Here. I'm unsure of what route to take? Please suggest me. Which one has more job opportunities for beginner? Or should I do a little bit of both?

Help with Helmfile rendering values !

Hey all ,


So In my current project we're using helmfile to do the deployments.

the helm file itself is very basic

environments:
dev:
values:
- sample.yaml

releases:
- name: api-users
namespace: orange
chart: private-hosted/api-users
version: v1.0.0
values:
- values/api-users.yaml.gotmpl


My issue is that if for example I make wholesale changes to `- values/api-users.yaml.gotmpl` . For example I can run

helmfile -f deployment.yaml diff
.....
....
...
ERROR:
exit status 1

EXIT STATUS
1

STDERR:
Error: Failed to render chart: exit status 1: Error: failed to parse /var/folders/cq/tcb7454j6qq67vgh1_wzl3c00000gn/T/helmfile412132336/orange-api-users-values-6f449f5557: error converting YAML to JSON: yaml: line 17: did not find expected node content
Error: plugin "diff" exited with error

The problem is although I'll get a stack trace of the issue. The value files generated are ephemeral and already deleted from the system before I can even check what values are wrong to create the issue

​

So my question is ..**And I'm aware of how silly this makes me look** (but can't find anything online) ...is there any simple way of generating the values files that will be produced when trying to do a helmfile diff/apply ?


Or even without getting to the diff stage , sometimes I put logic within the {{ }} and I would like to know what the resulting values would be but I honestly have no clue how to do it

Python vs Bash scripts in CI/CD pipeline

I’m creating a CI/CD pipeline for my organization. We’re running on OpenShift, so I’m using the OpenShift Pipelines (Tekton) operator.

Every example I see uses bash commands for the typical pipeline stuff (git operations, build commands, deployment, test runners etc), so I guess this is the standard way of doing things.

However, we’ve discussed using Python instead. Firstly, because it lets us unit test our steps, which will come in very handy when we’re updating/expanding the steps (which we’ll probably be doing plenty of in the first months - probably longer). We’re thinking of having a separate pipeline for our pipeline, so that tests are run automatically when we push changes to our steps.

Secondly, the organization mainly consists of developers, and not system administrators, so we figure Python is easier to both read and maintain.

Some (most I guess) steps will probably have a few more lines when we use Python modules such as subprocess, os and pathlib, but as far as we can see, it doesn’t really matter, because if the various pros mentioned above.

Any good reasons NOT to use Python in this scenario? Performance is also an issue (we obviously want our pipeline running as fast as possible).

How do I advance my career into higher level positions/management? (Design, Architecture, team management etc)

I want to move up. I was a systems/devops engineer for a few years now. I liked it at first but I got a little bored of it. I want to make decisions and lead a team in a direction that helps the whole department or something. I recently got into a role which is higher up but I want to go higher. What are the best steps to take/learn to accomplish this?

Analogy for when brew install goes wrong...

My co-worker dropped this amazing analogy for using brew install

I figured anyone here whose used a Mac and dealt with brew, might feel similar.

>using brew is like inviting the worst contractor into your house.

>me: Hi can you upgrade my bathroom sink?

>brew: sure can

>me: just checking in, how’s it going?

>brew: well i noticed you had other rooms in the house that share a common paint color, so i started upgrading all of them

>brew: your toilet might not work anymore


Anyone else feel this pain? or is it just us?

Asking full stack developer's that turned devops, was it an upgrade?

As every company does devops differently, it is common for management to think of devops as the team that does any of the following: sre, production on call, supporting developers, CICD pipelines, maintaining the cloud, operations, monitoring, etc... From my personal experience, these responsibilities (although are great to have) are a downgrade to a full stack developer. You may get marginal pay increase but for way more stress and more toil, combined with less respect

I know that a lot of people here would rather be a developer than in devops but there are also a lot of people that enjoy devops For those that enjoy the devops role, what part of the role do you enjoy more than being a full stack developer. Do people view you more as a person in operations or are you viewed as an architect (system design and interfacing with multiple teams)? What do you think your company does better than other companies who treat devops as operations

Fix WSL using random private subnets

WSL uses new random private subnet each time it starts. That may obstruct working with your work and private VPN, because - oops - sometimes the subnet is already is use, and will be until next reboot, and wsl --shutdown won't help you.

Here is my ugly hack to fix that: https://selivan.github.io/2021/07/12/wsl-set-static-subnet-hack.html

I got the idea from people in github issue discussing the problem: https://github.com/microsoft/WSL/issues/4467

Btw, WSL developers are determined to ignore that. Because somehow it makes WSL more newbie friendly. Like randomly selecting fixed private subnet, allowing to change it later(that's what for example VirtualBox does), would be less friendly.

Self-taught developer looking for guidance

I am in the process of deploying a SaaS based in the US (this is NOT a promo post) and I am using Heroku to host my Laravel application & DigitalOcean to host my databases.

As of now, the application is running with no apparent issues, including the customer onloading process. I am very uneasy because this seems a little bit too easygoing of a launch so I am looking for a checklist of sorts or just some sort of guidance on what I should be doing to test & ensure that the application is ready for production.

I am also a bit uncertain about compliance & data security requirements (if there are any). Any and all information will be appreciated.

Jenkins mapping 2 separately hosted Perforce depots. Failing to add any new files.

I've got 2 Perforce Assembla repos hosted on separate endpoints. I'm trying to map a few folders from one project to the other. ex: //DepotA//main/shared/folder to //DepotB/main/shared/folder.


I've currently got Jenkins pulling the two repos down into local workspaces and I'm using rsync to move files from one endpoint to the other. That part works fine. However if new files are added to DepotA's shared folders, when my pipeline does a p4publish, it will only update existing files and not mark new ones for addition. Does anyone have any experience telling Jenkins to, bascially, run a 'Mark for Add' command on a folder before a pipeline executes?

How can I get started with a career in Devops

Hello was recently laid off from my last position which has me currently looking for new opportunities.


I currently have a bachelor's in programming and 8 years of experience mostly working as a field service technician handling lower level networking and desktop issues.
My last job was a Tier 2 O365 Admin which I worked at for about 10 months.


I've been working on getting azure certifications currently have The Microsoft Certified Enterprise Administrator Expert cert and the Azure Administrator Associate cert. However, I've heard from several people that certifications are worthless without experience. Would the best strategy to break into the field be to just continue working on Certs while applying?

Query On granting Timed/ON-DEMAND access to databases

Hello folks,

We are using cloudsql in GCP and I'd like to provide a timed access to the databases to the end users. GCP provides IAM authentication to the cloudsql instance-databases, so each IAM user can login using his gsuite/cloud identity credentials.

I'm trying to make it as an on-demand access, i.e user makes a request via slack, the flask app (slack slash command redirect) takes the parameters to grant relevant access to the respective database. After 4 hours, the access has to be removed.

Currently I'm stuck at the expiration part. Unlike other GCP resources where removing users from IAM would work, here I have to login to the database and remove all the granted privileges for the user.

I'm thinking of store the access granted information in a database, have a script poll the db or python schedule functions watch out for the expiration time and start revoke actions. Any inputs on how to go about this? I'm going with the cloud native approach here, is there any better way of handling this on-demand access?

Basically, I know there is a loft sh and their o/s vcluster


Are there any open-source alternatives that allow to:


\- provision clusters in k8s namespaces


\- autoscale- put to "sleep mode" the pod & deployed resources on schedule

Anything you can recommend and are using now?

Reading metrics from not instrumented servers

Hi folks! I’m working on a tool for ad-hoc metric extraction and I’m really curious to hear back from the fellow DevOps people. I often find myself in situations when some metrics aren’t collected. Some servers may be simply not onboarded to the metric collection system yet. Some breakdowns may not exist because of the high-cardinality issue, especially per-pod breakdowns. And some metrics we just may haven’t thought about in advance. So, I hacked a tool called pq to parse and query logs as metrics. It seems to work and I have some ideas for further development. For instance, by adding a tiny HTTP adapter to it, it would be able to mimic Prometheus API, so one would be able to attach Grafana to an exposed port and query metrics from the UI. But before going any further with it, I’d like to hear back from the potential users.

Or just share your ways of solving similar problems, it’s also highly appreciated! Cheers!

Connecting to your Homelab without a VPN, SSH keys, or Public VP's using AWS Systems Manager Tutorial

The pandemic has made me enter the joys of home lab. I work daily as a cloud infrastructure engineer by day, so learning the home lab stuff has been rewarding. In addition, I have been trying to incorporate my cloud knowledge and skills into my lab environment by making a hybrid cloud approach.

I wanted to connect to my home lab remotely, and my cloud expertise makes me cringe at VPNs even though they have their place. It's just not "Cloud-native However, and I learned you could service in AWS to connect to private instances without the need for ssh keys, public infrastructure, or VPNs. There is a service called Systems Manager that offers a service "Sessions Manager".

I created a tutorial on how to set this up if anyone is interested.
