Anyone else feeling burned out?

Man I was so excited about WFH and all those cool projects but now they feel meh. Project after project, it just feels like another thing to do.

How are you guys coping with this?

Before this situation I’d have been travelling and discovering small parts of my province. However, for humanity’s sake I’ve been stuck at home for the past 10 months (WFH started early for us).

Bringing up my weaknesses

I've been a DevOps Engineer for 2 years now, no other background. Just graduated and went straight into a Jr SWE on an Infrastructure team which quickly became a DevOps team. In this time I've gotten to build docker images, GitLab and Jenkins pipelines, write Helm manifests for kubernetes clusters, administer Rancher (K8s orchestrator), and write/build IaC with Terraform, Packer, and Ansible. But what I havent done a lot of is Linux debugging/administration. Being so new to the industry I've always had seniors who would take on the more difficult debugging, whether it be network connectivity errors with out of band servers or kernel issues, etc. So, I think this is something I should work on more. What recommendations do y'all have for this area?

What's the DevOps take on "Delete Staging"?

I've been having a lot of conversations and have noticed a movement for "Delete Staging." The idea is that Feature Flags do the job just fine, just push to prod and puppeteer these features from the sideline. The thought is building and maintaining environments is frustrating, time-consuming, and takes resources away from the core product. As a startup or small company, resources are spread thin and you're just trying to keep your head above water as-is, so I get why people would try to cut this corner.

I'm curious what the viewpoint would be here from DevOps engineers on Feature Flags and Environments, what kind of success/horror stories you've run into, or just your intuition.

DevOps and Career Adivce

Hi Guys,

I need some career advice, here is some info about me

So currently I am 4x AWS Certified, having done the following in the past 5 months:

\- AWS Cloud Practitioner

\- AWS Solutions Architect - Associate

\- AWS SysOps Admin - Associate

\- AWS Developer - Associate (Perfect Score of 1,000)

I am currently studying for DevOps Pro and plan to clear it in January.

I am an accountant, switching careers and trying to make it into DevOps.

For this I have been studying for almost 2 years.

Initial Plan was to get into Full Stack (React / Node.js) Development but seeing the market saturation, I decided to get AWS certified and try DevOps.

For Front-end I know:

HTML / CSS (Grid / Flexbox) / JS (ES10), Typescript, React (Router, Styled Components, Redux, Cotext API)

Back-end I know:

Node.js (Express), Building REST API, JWT Tokens, SQL (PostgreSQL), MongoDB

(I built a small e-commerce website using this, along with Stripe API integration - adapted from a course I was following learning this. There are other small projects as well).

But seeing the poor market response, I decided to learn more about DevOps. This is when I started doing AWS and fell in love with the platform, and the power it offers.

I am focusing on AWS right now. But to be able to pass these papers quickly I built up my background knowledge. I followed COMPTIA's A+ 1&2, Network+, and LPIC 1 & 2 for some Linux knowledge, but did not appear in the cert exams for these courses.

Furthermore I plan to learn Python (I know basics already), Terraform, Kubernetes (Maybe get my CKAD) and Ansible.

I heard that AWS certifications are really valuable and some firms require people who have Professional Certs. That is why I am doing DevOps Pro.

Am I doing on the right path. Is there some career advice you guys can give on how I can get my first break? Will I be able to get a job if I have done these? I plan to finish all of this by Feb 2021 and get into full job hunt mode.

I am feeling a but lost now, any advice would be appreciated.

TLDR: Was an accountant, zero tech experience, started learning Fullstack JS, got interested in DevOps and started learning AWS, did all of the above, what do I need to do to get into DevOps?

Documentation Pipelines

We've have a documentation CI pipeline that takes Markdown and RestructuredText documentation from various repos and compiles them into HTML and PDF versions using sphinx. We've figured out how to do spell checking, but I'm curious if anyone knows of a way to do grammar checking? Could we enforce a third-person active voice throughout? I'm assuming we'd need the ability, like in spell checking, to exempt certain found complaints.


If you've done similar, I'm really interested in your entire toolset, not just your grammar checker.

Online OpSec: Threat models and tools for staying safe, private and informed while Online, used by the average person

DevOps and OpSec are relevant to each other in that security is, at least in my observations, becoming more central to software development. Instead of being thought of after the fact, DevOps teams are bringing security concerns into the beginning of the whole process.

To help explore the overlaps, [this GitHub resource](https://github.com/devbret/online-opsec) has been established. It features a growing list of techniques/strategies and tools for personal Online OpSec. Which carries over from both personal and professional life, one into the other.

The goal is to create a first class resource for everyday professionals to learn how Operations Security applies to them and what can be done. Feedback is encouraged here.

GitOps'y style with many repositories and submodules is kind of annoying..

May be a little bit niche but over the last couple of years we've been building up our new Kubernetes related service configuration in a sort of (in hindsight, the actual architecute grew relatively organically) GitOps'y way.

I'll start off on our repository types:

- Application source code (Bitbucket)
- Infrastructure configuration (Gitlab)
- Cluster configuration (Gitlab)

We have 8 Kubernetes clusters, which each have a repository for themselves
and within each cluster repository we have a structure which looks a bit like:

```
cluster-01:
apps/
platform-$service/
charts/
helmfile.yaml
.gitlab-ci.yml
deployments_$project_$container.yml
workloads_$project.yml
registries.yml
```

Each of those applications are essentially a submodule, and the deployments yaml file is created dynamically from the registries yaml file (basically, for each of the registries inside the file, search for every container we need to deploy, and deploy it).

However with 8 cluster repositories, and with every application being a submodule within those cluster repositories it can become quite labourious to actually make a simple chart change, or deploying a new routing change as it involes making the change, opening a PR for that change, and then updating the submodule, opening a PR for each cluster.

I've thought about maybe we can work within a monorepo for some of these things but I'm caught in a trap between being DRY and being easy.

Have any of you ended up with a similar structure? If so what did you do make it easier to use?

Alternatively, are you trying to solve a similar problem but solved it differently, I'd love to know how.

I'm not sure if I've explained myself particularly well so feel free to ask for clarification if needed!

Too Many Job Opportunities (Rant)

I completely realize that in this time of economic hardship for so many, this post will sound a bit tone deaf. I also realize this post reeks of privilege, and for that I apologize. I don't really have anywhere else to vent.

I am currently a DevOps engineer for a relatively small analytics company. I like my job. I like the diverse work I do, I like my team, I like my schedule flexibility, I like all my benefits, and I love what my company does. The only area that leaves something to be desired is the salary (which is largely offset by the great benefits).

Since the Covid pandemic started up earlier in the year, I've had a very noticeable uptick in recruiters and HR people reaching out about opportunities. In the last week, I've had over a dozen opportunities brought to me. This isn't counting the numerous random emails about 6-month contract work in Nowhere, Texas. These are legit, high-paying, interesting roles with really impressive companies; many of them fairly local, too.

Under better economic circumstances, I'd likely just stay put in my job that I like. As I'm the only person in my household working right now, though, it feels fiscally irresponsible to not pursue opportunities that would be significantly higher-paying.

Constantly replying to LinkedIn messages and emails to coordinate calls in between the minutes that I'm working, and trying to find holes in my schedule that permit panel Zoom interviews is exhausting. Constantly being "on" for conversations with recruiters and hiring managers is exhausting. Constantly thinking about trying to improve my situation to better provide for my family is exhausting.

Sorry for this rant. I was just curious if anyone else is experiencing this type of burnout (on top of the normal work burnout). Also, I'd be interested to hear anyone's thoughts on job changes/upgrades during this pandemic. How do you balance things like salary expectations, benefits, work satisfaction, company satisfaction, etc.?

Build/Deployment environment guidance

I'm looking for some guidance from the devops community here.

I recently completed the MVP design of an architecture for my organization's backend data collection, processing and persistence pipelines, only we don't have our CI/CD strategy finalized. We're currently on BitBucket/Bamboo and are likely going to be making a change and it's looking like GitLab may be what we move to.

The architecture is multi-stage (dev, test, qa, prod), multi-layered (data collection, enrichment/processing, persistence) and multi-region with some layers being in more regions than others. Aside from the complexity brought on by being multi-regional and multi-layered, it's a pretty neat, clean and simplistic architecture, that provides HA and somewhat easy regional failover, however the deployment is a bit intricate and of course because each region and layers needs to know about the others, each stack has dependencies on outputs from other stacks, in other regions.

My goal is to allow the developers to create their applications and be able to plug into the architecture. So, I'm using an EventBridge in each region/layer/stage that the developers can easily create a rule for the EventBridge to route data to their component.

Problem is, I haven't solved for the dependencies that the applications and their deployments will have on the infrastructure. I automated the infrastructure deployment using CloudFormation, and the developers typically use Serverless, so theoretically I can have all of the stacks export everything and let the developers just import those values everywhere they need them, however:

\- That creates a pretty tight coupling that I've never liked and Cloudformation is known for getting in these weird states that can be hard to get out of.

\- I can foresee developers wanting to depend on resources in other regions and Fn::ImportValue doesn't allow that.

\- Some of those values (i.e. "touch points") are needed at deployment time and others would be more valuable being obtained at runtime (Depending on them at runtime would allow human intervention in the event the whole thing goes up in flames, change the values and let all the resources "autodiscover")

I had a vision in my head that these touch-points (resource ARN's, hostnames, etc.) would reside in some key/value store that would be maintained in/by the deployment environment. When something gets deployed, its outputs would get stored in this key/value store. Even better, if the data store were backed by something like a DynamoDB global table, the values could be depended on at both runtime and/or deployment time.

Am I off base in thinking along those lines? Are there any frameworks that easily save these variable values and (ideally) persist them to AWS? I know GitLab has environment variables, but I haven't gotten a sense of whether they solve for what I'm thinking here. Should I just use Cloudformation Fn::ImportValue and cross the bridge of the above issues when I come to it?

Any guidance, pointer in the right direction, etc. would be much appreciated.

Thanks!

Any resource on AWS IaC with Docker?

Hi,

I would like to explore AWS using Terraform infrastructure as code. Is there any book (not a video) that discusses this topic?

I’m using Docker with Terraform on DigitalOcean and I’ve successfully hosted multiple sites online, but AWS Docker has a different nuance in Terraform. So what I really like is a tutorial or book that explains the steps simply.

I prefer to stick with Terraform rather than AWS CLI, so that my IaC is not coupled to any provider.

Also, this can be a paid resource.

How do you manage many resources with tools like Terraform?

We are looking at moving away from manually created infrastructure and going scripted. We have many projects and each has resources.

How does management of this work when using tooling like Terraform?

Should we just have many git repos? Should we use Terraform Cloud? Maybe we should use our deployment tool to assist? (Octopus Deploy).

This is new for us and there are so many options out there that it can be hard to understand the best route to take.

macOS taskbar plugin to monitor cloud costs

I am curious how do you monitor your cloud costs. Despite having credits, I have fear that I may exhaust it. AWS, GCP sends email invoices at the month end. Budgets and alarms is a solution. AWS has cost explorer API, but has limited information. GCP does not have a billing API.

How would you feel about a macOS plugin that displays your cloud expenditure and remaining credits in your taskbar. You can also customize it to show costs based on tags, resource type (EC2, S3, GKE). You can add any number of your cloud accounts from any cloud provider.

The user has to just enable billing exports and they see their cloud cost from menubar. Also, programmatic access to fetch their cost data so that they can integrate it with Zapier, IFTTT, webhooks.

DevOps last mile: automating edge cases.

Companies chasing DevOps have an internal team dedicated to automation. Developers use the tools created by this team to run and operate their code. They have many names, but let's call them Platform, which most companies do. Platform teams create abstractions on top of the infrastructure. The goal is to increase developer speed and make systems reliable. They increase speed by simplifying infrastructure APIs and reliability by automating manual tasks. But a curious thing always happens. One type of task that exists from the start of the company is always left behind in the automation backlog.

**Why automate?**

We used to ship software by accessing servers and running commands inside boxes to pull new code. Now code goes from Git to servers without human intervention. Developers define what they need with code. Platform teams build the tools to make code changes become running systems. The goal is doing this for everything, from the business code to infrastructure. Networking, databases, queues, etc. But this is hard. Platform teams have a big backlog, they prioritize items demanded with higher frequency.

Developers make manual changes for things not yet automated. Some companies have compliance, regulations, and other constraints. This makes it hard for developers to get direct access to production. So they have the Platform team running these changes for them. This is what makes the higher frequency items get priority. Engineers want to write software, not run repetitive manual tasks. But this backlog is never decreasing. The business changes and adopts new technologies. Companies create new units and teams. Headcount grows, adding new items to the automation backlog. And this mysterious type of task is always left behind.

**One-offs.**

Sometimes a bug in software messes with a customers' money, time, health, or ego. They won't wait for three iterations of code reviews, tests, code analysis, and gradual rollouts. This takes time. Someone will access the database and update it. These are one-off scripts. They solve a problem for one or a few customers before the team creates a definitive fix.

One-off scripts have a bad reputation. When this happens too much, it's a sign that the software is not stable. In the ideal world, it would never happen. Engineers would spot such time-critical problems during design and review phases. Production issues should be light and wait for regular software delivery flow.

Almost every company lives under the illusion that one-offs should not exist. Or that they will stop happening at some point. Yes, one should not do this every day. But having a few senior engineers run manual scripts in production because it's an exceptional case is a mistake.

**This is a myth.**

One-offs won't go away, and companies need to embrace it. Avoiding them will drive the company to a bad path. Either centralizing execution with experienced engineers or creating a team dedicated to analyzing and running them. This isn't good.

Some companies solve this problem with a slow and manual Change Management workflow. Developers find the problem and add a script to a ticketing system. Someone from the operations team runs it without all the context of what she is doing. Avoiding one-offs is the shortest path to this model.

**It's hard**

One-offs are the hardest piece to automate. When you don't know what problems can happen, it's hard to build a solution upfront. Few companies had the courage to 1) embrace one-offs, and 2) try to automate them. We did this for one of the companies I worked at, and it was a big success. Developers were happy with the autonomy to build and run all solutions to their problems. Security and compliance were happier with audit logs. SREs were happy with fewer manual interventions in production. It was hard but paid off.

I enjoyed the solution so much that I decided to bring it to other teams. I created a company; it's called [RunOps](https://runops.io). We help teams automate one-off scripts within minutes. We see fantastic results with

the first few companies using it. It's early days; our landing page is not clear on how we do it, so feel free to reach out on [Twitter](https://twitter.com/andriosrobert) or here to learn mode.
