what is the difference between ci and cd ?

hey guys, i'm working on a project where my data input is coming from google sheets automatically using sheets api then processed in order to get my final product which is a dashboard describing the total of sheets in the spreedsheet every week, i used for this python and streamlit and i want to deploy it on heroku, but i'm new to this, my question is how i can make changes later on my source code if i need to add a new feature without affecting the prod web app (dashboard).

thank you

Who wants to learn Kubernetes this weekend?

I had put a lot of effort in creating this video series (https://youtube.com/playlist?list=PLVx1qovxj-akr\_3XqQQgpqRyQw4GYuS4h) on Kubernetes for beginners. It consist of basics on kubernetes, creating minikube, kubernetes cluster, k3d cluster, Deployments, services, replicaset, HPA, Integration with Jenkins to deploy your application to Kubernetes cluster, kubernetes screts and more. .

I am sure this will help you to enhance your skills. I would appreciate a look on it :)

The best UI for log monitoring?

In terms of functionality, visual, etc. Is it Kibana, Grafana, or something else for you?

Monitoring and Metrics replacement project - looking for suggestions opinions

​

Hi all,

I'm a System Engineer with limited knowledge around monitoring and metrics working on a small team. I was handed a project to work on cleaning up what we have (SolarWinds) and gathering basic metrics for business critical items to be observed and shared within IT. I wanted to present my overall landscape and see what more knowledge folks had suggestion wise.

**The current landscape: \~**

* 200 servers
* 80 different physical locations (offices)
* fair amount of networking equipment
* 17,000 elements (data points/thingymajigs) in SolarWinds speak

We are using SolarWinds to monitor and alert via email and teams, nothing groundbreaking here. We have a mix of on-prem hardware, AWS, and Azure. For the most part it’s basic out Monitoring of servers and network equipment like up/down, CPU, Mem, Disk, bandwidth, with a few oddballs sprinkled in but nothing critical on the oddball stuff. We do have a bit of SQL monitoring and IIS monitoring but none of it is tuned in the slightest.

**The need:**

* Agentless (I know this is a limiting factor for greater detail)
* General cost on par with SolarWinds (not terrible because we are relatively small)
* Ability to the monitor basics above
* Need the ability to pull in data from other sources into a presentation tool such as Grafana. Some of the metrics I'm being tasked to pull in will not be easy or practical to pull from SolarWinds or Zabbix, or whatever we choose from the monitoring side. So the ability to pull in data from other systems, CSVs, APIs, or just text would almost be a requirement.
* The big "WANT" is, 1 central place to display & present the data.

I’ve started looking into things like Zabbix + InfluxDB + grafana, PRTG, (Datadog soon), and generally lurking in this forum for the last few weeks researching stuff. But as with a lot of us out there in the business this isn't my primary responsibility so there is only so much brain space to devote to it :).

As an aside, SolarWinds is pretty quirky and clunky but does things “OK” as my org needs them. I’m pretty sure with a stupid amount of work i could make SW do most of what needs to be done. But the level of effort involved there might be 2-3x more than dropping in multiple other systems.

Service Meshes - Reasons to avoid them?

I've read a lot about Service Meshes and like a lot of the possibilities but have seen a lot of things saying they should be avoided until absolutely needed.

I haven't seen good descriptions of why, however, outside of "it takes a lot of effort".

Can someone explain why it wouldn't make sense to start out with a service mesh with defaults and then invest in individual features when it makes sense?

Are there legit horror stories or is it just scars from early adopters that have been mostly worked out?

I'm Implementing DevOps in my Organization. Which CI/CD tool to prefer

I'm currently asked to choose from one of the three Jenkins, GitHub actions and Travis CI to use as CI/CD tool but I don't know much about any other tool except for jenkins.
My organization is a growing startup, all the codebase is in GitHub and currently I'm the only DevOps person who itself is an intern. I really don't wanna do something that will haunt me back later.
Any suggestions??

Edit: I'm highly familiar with Jenkins though

most cost-effective backend

my backend runs fine on a high-end consumer-grade computer. It doesn't need a GPU. I am wondering what is a cost effective backend service. AWS ec2 seems too expensive.

Azure Devops > Simple File Copy with Deployment Groups

I am defining a Release Pipeline - and I want to simply copy files (the deployment assets) to a directory on the remote agents (on-prem). I do not want to specify credentials. The deployment agent should pull the assets from Azure, similar to how the "IIS Web App Deployment" task group works.

This is a simple console app that I am deploying. I cannot find an appropriate task to do this. Anyone have any ideas?

Are “devops” salaries stagnating?

A decade ago if I made rhe mistake of picking up the phone when a San Francisco headhunter called I would ask for their salary range out of curiosity before I hung up, it was always $140k-$160k.

Today it seems to be $150k-$170k, unless you’ve written books or promoted the hell out of yourself on twitter.

I make almost twice that consulting on managing offshore eng orgs and would never consider a real job again, but why are salaries so low and stagnant in a city where the cost of housing has doubled in 10 years?

they would give me a $140k-$160k salary range and I would hang up.

10 years later I’m given the same salary range

How does Circleci compare to github actions and gitlab

longtime lurker here... not a full time dev ops but noticed that most people prefer GitLab or Github actions... I have been using circleci for a while now... wondering if i'm missing some features staying with circleci, so wanted to get some input... We use cci to run a pipeline to k8s cluster, i can create a new cluster in few lines if needed.. also creating docker images and pushing them to registry is pretty seamless...

Whats the hive mind input on Circleci?

My company is starting git, how screwed am i?

Let me explain. Against my stern warnings, they are instituting an environment based system. So the Item is done on local branch, it gets merged to test. Where it gets crazy is from test to stage. They are going to cherry pick each individual item from test into stage. Never merging.

I personally am in charge of implementing this. Are we as screwed as I think we are? Will we be solving merge conflicts on every cherry pick? Should I just get it over with and shoot my foot right now?

Pretty much I want to know from people who might be more experienced than me if this is as bad as I think it's going to get? Am I just nervous and overexagerating?
