What is a cool thing I can show high schoolers who learn programming that will be interesting to them?

Hey all,

I'm a DevOps engineer and I got this feeling that I want to go and volunteer somewhere.

I came up with the idea to go to my old high school and show them something DevOps-related that they might find interesting and if any of them want to, I could teach them a thing or two.

Now I'm trying to think what in our field would be interesting but simple enough that high schoolers could enjoy.

I could always just do a docker demo or IAC type of thing but I don't know if they'll find it interesting.

What are your thoughts?

Best monitoring tools for clouds?

I would like to know if you have used some monitoring tools and what are the best for cloud like Azure, AWS, GCP, etc. I would like to implement and monitoring my resources like the VMs, the networks, the infrastructure, the security, the applications, etc. in the different clouds. I have read that some goods are datadog, appdynamics, instana.

Which is better ?

Do you think it's more a enriching experience to work as a DevOps consultant and getting to work on a lot of different projects or as a DevOps engineer working on same company projects ?

How Quickly does your org react to change? How is the decision made to adopt new technology on the market?

I've been interviewing for Kubernetes focussed roles lately and I've been wondering, how companies even knew to make the switch before adoption was widespread? Who are these early adopters with 5+ years of experience and how do they know when a new technology is going to come out ahead? How do you convince your org to switch when an emerging technology is on the market? Just curious what the thought process is in general.

How do I show a devops portfolio?

I am learning devops and want to get a job in the field. It was suggested that I put together a portfolio.

I have a website I can put it on, but I don't know what it should actually be.

Other than links to the github repos where the dockerfiles, jenkinsfile, and helm charts I create are... what could I actually show? I usually fork a java or node repo and then add all of the pipeline and docker files to it. Should I have screen shots of the command line outputs showing everything is running?

HAProxy+xinetd+galera - Connection reset by peer

Hi guys!

​

I have a simple galera with 3 nodes and a haproxy lb. I use xinetd for the check and my problem is that every X check return with this error message: Socket error: Connection reset by peer

image: https://imgur.com/a/Jkf44HX

haproxy config:

# MySQL Cluster BE configuration
backend pxc-clusterbackend
mode tcp
option tcpka
balance leastconn
option httpchk
server pxc-cluster-node-1 192.168.0.130:3306 weight 1 check port 9200 inter 1s rise 2 fall 3
server pxc-cluster-node-2 192.168.0.170:3306 weight 1 check port 9200 inter 1s rise 2 fall 3
server pxc-cluster-node-3 192.168.0.182:3306 weight 1 check port 9200 inter 1s rise 2 fall 3

#####################


xinetd config:

# default: on
# description: mysqlchk
service mysqlchk
{
# this is a config for xinetd, place it in /etc/xinetd.d/
disable = no
flags = REUSE
sockettype = stream
# type = UNLISTED
port = 9200
wait = no
user = root
server = /root/mc.sh
logonfailure += USERID
onlyfrom = 192.168.0.0/24
persource = UNLIMITED
}

In the script i just make a simple select and if success return 200.

I also tried to add the haproxy address in the /etc/hosts.allow file but nothing.

Have you any suggestion?

Tell me your opinions about full-stack monitoring solutions

For those of you who have used multiple monitoring solutions, I'd like to hear your experience and your opinions about which is best and why. To be specific, I'm talking about solutions which offer log aggregation, host metrics, application metrics, APM, outside->in monitoring (synthetic checks), and alerting.

I've looked at Elastic, DataDog and New Relic. I think New Relic doesn't hold the prestige it once did. I'm my opinion, it has fallen behind it's competitors and become more of an enterprise solution. I have used DataDog briefly, and am a long time Elastic user/admin, but have never used the paid versions so no APM or "AI" features (correlation, anomaly detection, etc).

What do you all think is the best of the three, and why?

ETA: If I'm considering Elastic this time around, the paid features are definitely on the table.

How to transition from IT Analyst to DevOps?

Looking to possibly transition into DevOps.

Past:

Help Desk
NOC tech
Point of Sale Analyst
Web App Server Implementations
IT Analyst /Incident Manager at a Fintech (current)

10 YOE

I work with DevOps on a regular basis and it feels like it would be a great next step. Both in career growth and in compensation.

Figured I’d ask Reddit, what’s the top 3 things I can focus on to land a DevOps role?

GitHub actions? Azure proficiency? Python for automation purposes? AWS?

Thanks!

Best paas to host a wildfly aplication?

Hello everyone, in less than a week I need to put a wildfly application on one paas. It is going to be an ear and it also uses remote jms queues. There seems to be a lot of options but most of them dont support wildfly out of the box. The service has to be free because it will be used for testing for now.

Limitation for consul-template to discover changes and invoke reloads in HAProxy.

Hello there,

I'm refactoring old consul-template (further called just consul), that generates HAProxy config and my goal is to reduce amount of reloads to minimum. Currently whenever service is being auto-discovered due to its auto-scaling, consul reloads my config. I'm also switching from static config generated by consul at every service change to so called haproxy server-template with KV for slot configs.

But I'm struggling to find any information related to how to limit consu to watch only KV changes not service changes.
- Is it like if something is used in config then consul watches for changes there?
- Or is it being invoked after every small change?

Best storage solution for normalized relational data if I'm locked to GCP?

Hey /r/devops

Got a GCP question. If I have data that is relational and highly normalized, what's the best option for me on the platform?

I'm using BigQuery a fair bit in the same project, but the data I'm dealing with in there is completely denormalized, which the BigQuery docs says is the way to go.

The relational data that I'm storing isn't actually going to be queried often - instead my server running in prod will sync with it from the cloud every hour or so, and that's where the bulk of the live querying takes place.

What I'm looking for is a place to keep my data in the cloud (specifically GCP) so I can back it up often, query it offline, sync with prod/staging/dev environments. Should I still use BigQuery if I'm not querying the data from there often, but just using it for "lukewarm" storage to be pulled down elsewhere?

---

Edit: for context the relational data isn't huge. It's a bit under 30mb at most. The other stuff I'm doing with BigQuery is dealing with gigabytes of denormalized data (so I'm already using it in this project for other stuff)


---

Edit 2: Having the SQL interface on the data is still important - I'd like to query it while it's in the cloud as well (on top of the other stuff I mentioned like pulling it down into prod/staging/dev environments to be consumed by Postgres for example).

MAAS set default cloud-init script

I have a MAAS server that deploys Ubuntu workstations.

Provisioning a preconfigured Nexus Repository Manager (NXRM) Docker container

Hi all, I've created a preconfigured NXRM Docker image, with an init-script - provision/entrypoint.sh,

Link to project @ GitHub - https://github.com/unfor19/nexus-ops
Link to Docker image @ DockerHub - https://hub.docker.com/r/unfor19/nexus-ops

Here's a TL;DR of what the entrypoint.sh script executes upon running NXRM:

1. Changes the initial random password that is in /nexus-data/admin.password to admin
2. Enables anonymous access - allows anonymous users to access localhost:8081 with READ permissions
3. Adds Docker Bearer Token Realm - allows anonymous pulls from local Nexus registry localhost:8081
4. Creates two Docker repository of type proxy
1. docker-hub - DockerHub
2. docker-ecrpublic - AWS ECR Public
5. Creates a Docker repository of type group
1. docker-group - The above Docker repositories are members of this Docker group

How to make a social media app for your community?

The industry of mobile app development for social media is continuously growing. For example, Instagram is visited by over 500 million people every day.

And it’s never too late to come up to the market with a new exciting idea. Most people are always open to something new – just look at the enormous popularity of TikTok with 1.5 billion installations or Clubhouse that is currently #5 in the “Social Networking” category of Apple’s App Store and will be released on Android soon in 2021.

These days, you can build a digital network for entertainment and communication (e.g., to post short videos and find like-minded people), for business (e.g., a real estate social network), for sharing opinions, etc.

Do you want to create your own mobile app for social media? This article will provide you with essential information on the industry’s specifics, an app’s features, and development processes.

Before making a plan for how you will make your app, it’s helpful to gather more information on different social media, the prominent trends, and users’ expectations. You should also discover what metrics are useful to assess the popularity and how to make money with an app.

>“Social media is not a media. The key is to listen, engage, and build relationship”David Alston, author and entrepreneur

Indeed, social media are different from classical newspapers or TV channels. You need to create a community and actually engage with people, which gives you lots of challenges and even more benefits.

1. Interacting with your community directly. Once you create your own platform and a social media app, you establish the rules and communicate quickly and effectively, without any mediators.
2. Advanced user analytics. When you make a social media app, you can better understand your community, use smarter target strategies, and operate all social media marketing tools.
3. Built-in e-commerce options. With a customized social media app, you can easily monetize certain functions or add one-click purchases.
4. Safe spaces for creative and innovative ideas. Post and comment length, content types, functionality, or design conception – there are no limitations if you create and run a social media app by yourself.
5. Maximized reach and no distractions. If you make a bespoke app, you can operate social algorithms to show users more quality content based on their interests. There won’t be any distracting information (ads, news, memes) from widespread media, just you and your community.

All of these will be the result of bespoke mobile app development for social media. You need to elaborate your business idea and find a team of experienced designers and developers. And first of all, choose the niche to create a social media app.

HOW DO SOCIAL MEDIA WORK IN 2021?

>“The first rule of social media is that everything changes all the time. What won’t change is the community’s desire to network”Kami Huyse, PR & social media strategist, CEO of Zoetica Media

What earlier trends are still relevant:

Chatbots and artificial intelligence technology – though these trends appeared in 2017, they remain in demand among social media apps users.

Brands’ engagement with customers – people more often use social media as quickly working client support, while companies invest in reliable social media presence.

Social commerce – Facebook, Instagram, and others offer multiple tools for businesses and allow people to buy goods and services directly via social media.

Blogging on social media – people and brands publishing engaging content and share it with as many users as possible.

Once you have chosen a niche for your social media app, it will be easier to select its features and marketing strategies.
