Learning path

I’ve been a data scientist for about 2 years now and only worked mostly with raw data and modeling, but now at my current role I’m being asked to run also the deployment part with techs like docker, Jenkins, Argo etc and recently I’ve been asked to learn about Prometheus and Grafana.

I didn’t have much time to even dig deep into docker and I feel like I can’t even gasp the basic knowledge of what each tech piece does, its purpose and in which part of the deployment tray it fits.

So, I wanted to know if you guys could start over how would you gasp the devops environment and it’d be pure gold if you could add a free courses as a recommendation

Needing to work with developers to fix something feels like asking them to do sidequests.

How do you guys handle tickets that require time from developers? I have a couple of Jira tickets that require either knowledge from specific developers to help fix something they created or require them to modify something in their code.


The problem I'm facing is that I need to chase them down to get them to help me and there's really no consequence if they decide not to. Boss doesn't seem to think this is an issue since they have their own tickets that they're working on, but my Blocked tickets are piling up and they have my name attached to them.

Database user management?

Are there any tools that help automate the creation of users and granting of privileges on databases/tables?

I'd love to have a web-based UI that users can access via SSO, where they can request creation of users or granting of specific privileges. Admins would be able to approve these requests with a click and the tool in question would run the CREATE USER or GRANT queries, as well as keeping an auditable log of said operations.

Does a tool like this already exist?

If not, is there a reason why it shouldn't? I.e. would this be an anti-pattern for some reason?

For context, we build a lot of microservices, and create service-specific users and grant the privs needed for that service. However, this is all manual currently which leads to a lot of grunt work for our devops team, and is hard to audit (currently devops engineers post the queries they ran as a comment in the JIRA ticket requesting the db user/grants).

TIA!

CI/CD server script question

When you are writing an inline script on a CI/CD server like bamboo, how does it know what location in the server to start the commands from?

For instance, in one of our scripts, the first command is cp. Which directory is this command being run from?

Why do some people say DevOps would be one of the first fields to be replaced by AI?

Not saying i believe AI will take all our jobs but from what i heard dev ops is much less about coding (what AI does relavely well) and more about infrastructure, support, communications and automation.


I mean the whole point of DevOps is to use tools to automate processes, if anything AI would just open more doors.

Also I heard DevOps requires a lot more communications and soft skills, which mean harder to replace with an AI.

What do you guys think? If AI does a lot of Damage in the Software market will DevOps be more/less/equally impacted?

Which centralised key/value store datasource are you using ?

Pretty simple question, which centralised k/v store datasource are you using ?

​

For context, I am currently using AWS parameter store to share informations across multiple repositories. This being provisioned and queried by terraform but this one does not seems reliable as it happens to sometime create the new value before deleting it within a value update flow.


I was previously using Hashicorp consul with whom I never had this kind of issue but is another whole topic to deploy and maintain. I am wondering if you guys have others tools to handle this kind of flows.

Grafana to sumologic pricing


So currently our company hosts a kube prom stack , we host 3 Grafana instances for Dev,staging and prod . I have set it up to collect metrics , Loki for logs and tempo for tracing but it has got no adoption from developers .

They are looking to switch to sumologic ( they use it for logs ATM ) but I'm wondering how much it will cost us to send metrics up , confusing how this is worked out .

For prod our tsdb shows :
Number of series : 900k
Scrape interval : 30s

Sumo is 3 credits / 1000 DPM
1 credit = $0.15

I'm getting crazy cost here . But what are we looking at per day / month or year roughly .

Thanks

How people generate examples for multiple programming languages?

I need to generate classes for C# and java with some constants based on a json document. Is there a tool to convert some language agnostic model to classes of a specific programming language?

Offsite Openshit Redundancy

Hi all,

I’m trying to picture how I can set this up. I have an openshift cluster (OKD) that hosts a large amount of websites. We also have rack space at another location that we want to have backups of some of our openshift projects (core website, etc). Any thoughts on how to do this? I’m struggling reading through documentation.

Building Unprivileged Multi-Arch Images Using Kaniko and Gitlab CI

Hey r/devops!

I know people aren't big fans of having work blogs posted here, but I recently tackled something that didn't have much documentation online and wanted to share in case this could help someone else!

Amongst other things, I used some pretty cool, as of yet, undocumented gitlab CI features that allow you to change your gitlab runner's node selectors through environment variables in jobs.

Running SuperTokens self hosted on Kubernetes at scale

Hi, I've always written my own Auth services and ensured they were cloud-native and scalable (horizontally). I'm about to start a new project and I'm drawn to trying out SuperTokens.


Anyone here with experience deploying supertokens on kubernetes?
Is the image (registry.supertokens.io) designed to support multiple instances running in parallel, connecting to the same database?

The Case for Function-Level Metrics: An observability sweet spot that balances debuggability, cost, and ease of use

Hi all, I was inspired to write this up after reading a post from Cloudflare about how they run Prometheus at scale. They mentioned some of the engineering challenges around managing the full life cycle of metrics, and I think function-level metrics address those challenges in some kind of neat ways.

How do you read books to learn?

I'm really curious. I haven't learnt anything till date just by reading books(and practicing). I always required some form of videos to learn. Neither do tutorials websites work for me. How do you read books?

I'm having to read this book in short duration(as I'm in job) ""The Linux System Administrator's Guide"", how do I do it. I have at most 2 weeks to read that book. 2 weeks, 9hrs per day.

Terraform, AWS, and user management

Does anyone have a good way of notifying new employees about their IAM account and what their temporary password is?

I see that there is aws_iam_user_login_profile but it doesn't actually send the temp password anywhere. Should I use something like local-exec and just send an email template?

Any thoughts would be appreciated.

What is your methodology when dealing with IaC on a cloud service?

I’m using Terraform as my IaC tool, and find it very hard to setup the right configs, especially for cloud services I don’t use often.

Is there any proven methodology? I tried doing things on the console to get hands dirty on the services, however sometimes the Terraform parts are more granular and I can’t get a 1-to-1 equivalence between the console and TF parts.

What are your tips?
