Check out a practical approach to Dev Ops

When we talk about ecommerce success, we’re ultimately talking about software success. Software isn’t just a key part of your business; it has become the main differentiator between you and your competition. How quickly can you build your software? How quickly can you deliver it to your customers?

kubernetes - my fingers are tired

How can I execute CLI commands like get, describe on pods, view logs, etc. without having to retype the same commands over and over? Also, for others who are using Kubenetes how many people are managing your cluster(s)? What are some useful integrations?

Questions to ask a company on how they perform devops

I know that devops isn't supposed to be a role or a team but it should be a culture. However, we live in reality where lots of companies perform devops differently.

What are your go to questions in filtering for red flags when asking a potential employer how they do devops. What are some good and bad answers? When you see the red flags, is it a show stopper for you?

I assume that FAANG type companies do devops better than most, although not perfect. I am not I am focusing on these companies but small to medium sized companies

Metrics from logs. Why?

I know a number of teams that seem stuck on the idea that they need metrics from logs. Not having enough context for why that would be necessary and given the cost of doing so (i.e. - efficiency of metrics over logs, latency incurred from transforming logs into metrics, etc.), can anyone here give me some insight into how a distributed system would benefit by using metrics from logs (like a business use case)? I totally curious why I keep running into this. I feel like I'm really missing something here (or maybe I'm not).

Terraform or Ansible or both for cloud deployment ?

I have test Terraform and Ansible to deploy some virtual machines in Azure because I would like to automate the creation and deployment of resources in the Azure cloud and soon probably in AWS, but I don't know with which one of those two pick to use in my daily work.

I have read that DevOps Engineers recommend use both but I would like to know what are the key difference between Terraform and Ansible and if it would be better to use both or only one

Questions for those who work in DevOps

* What's the best thing about DevOps, and also what's the biggest challenge? What does DevOps mean to you?
* For how long have you been working in DevOps? How come you got into it?
* What did you do before? What experiences, previous jobs, knowledge, etc would you say is needed/good to have before pursuing a DevOps career?
* What are the top skills needed to become a good DevOps engineer? Does one have to "eat and breath technology"?
* Have any of you left DevOps, and how come?
* Would you say a DevOps role is a good first job for someone who just graduated, why/why not? Would your workplace employ less experienced people or is it just for seniors/specialists?
* Any tips for someone who just started working in DevOps (coming directly from uni)? No previous experience and feel like a fraud lol. For how long would you say an inexperienced is new at a job?

ECS vs EKS?

Or rather, Fargate vs Kubernetes. Maybe I never worked on a project complex enough, or maybe I try to build my infrastructure in a simplistic way, or maybe I simply don't know enough about Kubernetes, but I don't know of any scenarios where Kubernetes would be a better fit. I think it's basically a cloud within a cloud, and unnecessarily complex. It was useful while we were orchestrating over on-prem servers, but now that we have cloud providers where we can describe infrastructure with auto-scaling rules, Kubernetes seems outdated. Am I missing something? Price aside, when, if ever, would u pick Kubernetes over Fargate?

How to connect remotely to mysql running inside a digitalocean droplet

I have a mysql instance running inside a digitalocean droplet. Originally, we also had a laravel application running inside that droplet with the mysql instance but now we want to move our application to kubernetes.

The application has been deployed to kubernetes and we are trying to connect the laravel application to the MySQL instance inside that droplet for the purpose of testing but we keep getting the error:

Host '46.101.81.14' is not allowed to connect to this MySQL server

That is not IP address I specified as the host, and it is not the IP address of my kubernetes loadbalancer either.

These are the steps I took to enable remote access to the database:

set bind address for MySQL to 0.0.0.0
CREATE USER ‘someuser’@'localhost’ IDENTIFIED BY 'password’;
GRANT ALL ON databasename.* TO remoteuser@'ipaddressofk8s\_lb’ IDENTIFIED BY 'password’;
sudo ufw allow from ipaddressofk8slb to any port 3306

Please what could I be missing?

Best practices for external containers

Working on a couple of projects where we may be getting containers from vendors/partners or pulling them from places like Nvidia. Some to use directly, some to build into home grown apps.

Anyone have best practices to share on managing them?

Should we use them from provider registries? How do we make sure they are available and that we are all using the same versions?

Should we setup our own registry and manage the lifecycle ourselves? What should we setup? How do we keep them in sync with external registries?

Has anyone dealt with licensing? Should we expect license files or license managers for closed source software? We haven't asked so looking to be prepared.

Thanks for the help.

Will Continuous Design / Continuous Integration be a thing?

Hello everyone,

Over the past few months, I've been really digging into many of the common trends we've seen over the years relating to developer operations. I had observed that so many different processes were being automated in the developer lifecycle, but the design to development process has not, or at least not really. I had some hunches, specifically with UI/UX design to development that there are startups trying to fix this. But after digging into other types of design, I became interested in the idea that we could see many other toolsets that could aid other types of design (Architecture, Database, etc). As a play on words, I called this, "Continuous Design / Continuous Integration". I'd really like to hear the feedback of this community. I may be completely wrong but I love the idea of integrating all types of designers into the developer workflow. I share a good chunk of my research and thinking here: https://parabeac.github.io/CD-CI/

Frontend programming question regarding featurebranching (DevOps way of working)

Hi guys, Im extremely new to Frontend programming and I have a question regarding DevOps best practice. Im creating a website using html css and js. This frontend does have to query out some information from backend APIs. We have dev, sta and prod, all deployed from the main branch, and people do pull featurebranches from the main branch, which usually results in deployments on the dev AWS account but with a featurebranch package. These featurebranch packages do not have that many dependencies, and if they have, they consume the main branch deployments on their respective environments.

​

The question I have is about featurebranching in the Frontend.

I notice a lot of people use environment.ts files in Angular like frameworks but that all is buildtime information, not runtime, and it feels incredibly static to me. In DevOps, shouldnt we try and look up this information more dynamically? Are there services that could help here, like AWS Cloud Map or Consul? Or do you just have to change my environment.ts file like stuff, repackage and redeploy on a featurebranch if you would like to access a different API Gateway endpoint for development purposes?

Any insight might be helpful. I have the feeling that backend frameworks have a lot more support build in for modern way of working than current frontend frameworks have. Also, it is not an option to just drop featurebranch support and claim the entire dev environment for myself since we have a ton of guys working on functionality.

Thank you in advance for some guidance. I can learn a lot from it.

Exposing VPC/API gateway to a slack specific DNS

I have a slack bot which is running on a EC2 in a VPC.

The VPC/ API gateway is supposed to only be exposed to slack (for slack event listening), Its not supposed to be publicly accessible.
How would I filter based on slack's DNS? https://api.slack.com/robots

I saw that API gateway has resource policies however they are only IP\ AWS account\ VPC based.

Any other AWS services that can help?

Setting up a server with Linux/bitnami/docker/jenkins

Hi!

I develop Django apps and want to set up my own VPC but want to understand some things first.

I've used bitnami on AWS previously to host a Django app which worked good. So I think that maybe I can install bitnami on the Linux server i want to rent first.

Then I guess I want to use Docker to contain the environment I develop in.

Then I want to use Jenkins to manage testing and CI/CD.

Does this above make sense? Am I misunderstanding some of the parts or am I missing something?

Do you consider Devops as more of an art of science?

Obviously Devops focuses on using tools and solving problems using automation and hitting goals like faster releases.

However to be effective and good at the role is creativity and bringing new ideas also important? I ask because it can seem like just hitting and requirements and going off a specification sheet.

But there are many different ways to implement a solution and trade offs with each. Some people use terraform, others extend with Terragrunt. And then you can use Helm to update your stack, and CI will take care of everything. If you follow a different approach — say letting the systems get too complex then that becomes difficult to manage.

So how do you design the approach to be efficient, but also practical as well. As you add more features and things you want to do using tooling, then seems like more things can go wrong but that’s part of software adding new features and iterating.

In reality the end goal isn’t always desirable— I look at same an ambitious project like the game Cyberpunk not delivering on promises and being half baked. So is it the culture or processes that need to change? Because sometimes your org can’t agree on simple things and ask to cut it or go with another idea.. you see how this adds up with the final result becoming divergent from the original plan/idea on paper.

Any recommendations from knowledgeable practitioners on how to use good practices but also implement clean and agreeable design patterns?
