Those books are great. O’Reilly has most of them via subscription at work for me. We also have a Udemy business subscription to do training for AWS, Cloud, Python, etc…

I recommend: “War - Peace - IT by Mark Schwarz”, “How to Win Friends and Influence People by Dale Carnegie”, and “How To Lead When You’re Not In Charge by Clay Scoggins”.

I’ve recently bought an O’Reilly book: “Technology Strategy Patterns by Eben Hewitt” and have just started to listen to “How To Lead In Product Management by Roman Pichler”.

I know, I know… not very tech focussed but I believe it’s never a bad thing to understand people, behaviour and some of the “softer skills” aka how to not be a d*ck.

Hello, is someone here with experience in Jitsi(Meet)? I am recruiting help for a long-term project.

RB avatar

Love using jitsi. What do you need help with

rei avatar

Have you used a turn server? For a firewalled setup with only port 443? Afaik I need 3 servers (3 public IPs): nginx for jitsi-meet JS and config; one or more video bridges; and the turn. Each service listens on 443

RB avatar

Hmmm i haven’t gone that far. Ive only used the free jitsi app with groups with maximum 10 people

Is there an advantage to hosting your own vs using theirs?

Mostly same as https://github.com/cloudposse/prometheus-to-cloudwatch/issues/10#issuecomment-446738814 , but since https://kubernetes-charts-incubator.storage.googleapis.com/ is no longer available, I changed repo url to new one.

Besides the Phoenix project and the Google sre book, does anyone have any good sre/devops book recommendations?

Andrey Bronin avatar
Andrey Bronin

Can you suggest Phoenix project to an experience DevOps engineer? Is it useful or more for fun?

RB avatar

I’m pretty experienced. Been doing sre stuff for a few years. Everytime i read a book on this stuff, i personally think differently

RB avatar

In short, yes I’d recommend it

1
Joe Niland avatar
Joe Niland

There’s a lot to understand in that book. It starts off easy and then gets pretty dense! I read The Goal too, which is what The Phoenix Project is based on - that’s even more dense Definitely recommended though.

I haven’t made time to read lately but I am planning to pick up books from Jez Humble, Nicole Forsgren among others

Andrey Bronin avatar

@Joe Niland I agree, “The Goal” is great. Note: It’s not related with SRE directly nor with IT.

Alex Jurkiewicz avatar
Alex Jurkiewicz

Following on from the above question – very few SRE resources talk about how disaster recovery work. Mostly they assume you are Google scale, and you don’t need explicit disaster recovery because you are big enough for all your applications to run in a globally-distributed, fault-tolerant manner. But I work for smaller businesses and need to think about “what options do we have for cross-region DR?” and “how much do we want to spend?” and “how do we maintain this DR process?” Any suggestions on how to look at this from an SRE perspective?

loren avatar
loren

i like to start with breaking it down into dependencies and state. dependencies are all the services and software you need to deploy/run your system. state is all the data you need to backup/restore to run your system. that’s generally the easy part, really, but it helps frame the problem. i.e. are all the dependencies available in primary and DR regions? do you have backups of state? do you test restores from state? can you deploy using a restored state? etc…

Chris Fowles avatar
Chris Fowles

for the how much you want to spend - see if you can get that back to a “cost of loss of service” metric - that way you can look at the risk vs the cost and determine how much you want to spend to mitigate that risk

1
Ives Stoddard avatar
Ives Stoddard

@: you can start with some high level estimates. double the cost of your current environment, but scale down the remote DR side (run two instead of 12 web servers for example, run on slightly smaller instances to maintain replication). Do this for production AND staging. Double the cost of file & DB storage, snapshot storage, S3, etc.. That’ll give you a rough idea of infrastructure costs. More or less depending on how thing you want to provision the remote side. You can look at things like EFS (filesystem replication), S3 replication, or Aurora cross-region. Those might increase your costs a bit if not already running them.

Ives Stoddard avatar
Ives Stoddard

Work with your business side of the house to calculate risk/cost and decide on a target RPO / RTO, then figure in the engineering resources to implement your targets.

Ives Stoddard avatar
Ives Stoddard

The least data loss & service downtime will be the most expensive to implement (requires live replication vs. 24-hour snapshots for persisted data). Additionally, will your application or services need to communicate across regions (failover testing, planned failover, etc.)? If so, you will need to test and potentially modify the application to avoid stacking latency (multiple round-trip API calls in serial). You might do this if you have lots of applications / microservices and need to test / migrate them independently. It is simpler if you have a 24 hour RPO, just start new services on remote DR side and flip DNS.

Ives Stoddard avatar
Ives Stoddard

If you need lower RPO, or seamless DR, be sure to practice it on a regular basis. Infrastructure changes, configurations change, whereas your documentation might not. Create run books and checklists, and verify they work. Schedule regular downtime for it if possible (annual, twice a year, or quarterly, depending on how low your RTO/RPO is).

Is there helm repo for https://github.com/cloudposse/prometheus-to-cloudwatch ? Looks like there isn’t. and I need to clone this repo by myself to be able to use from terraform helm provider?

cloudposse/prometheus-to-cloudwatch

Utility for scraping Prometheus metrics from a Prometheus client endpoint and publishing them to CloudWatch - cloudposse/prometheus-to-cloudwatch

t.hiroya avatar
t.hiroya

Until the chart is available in helm repo, I do something like this to put the chart in my own git repo, so that terraform can read its content… git remote add prometheus-to-cloudwatch <https://github.com/cloudposse/prometheus-to-cloudwatch.git> git subtree add --prefix=prometheus-to-cloudwatch prometheus-to-cloudwatch 0.14.0 --squash

I have searched through the archives and google is not helping either… so hopefully this isn’t described somewhere I have just missed. I am working on setting up a new infra utilizing cloudposse OSS but have bumped into a few issued. I got all the accounts setup and that is working great, also got EKS and other application backing services up (eg RDS) all using terraform… but I am having troubles finding out how to make the next steps through IaC.

In particular I am trying to get Codefresh setup for GitOps but it is not clear how to do this as IaC. I got my Codefresh account setup (using Github to auth) but to add the K8s EKS integration for example I used the helm chart (cloudposse-incubator/codefresh-service-account ). But I did this by hand which seem wrong. Then to setup the project and pipelines I can only find how to do this by hand.

I am working through the cloudposse/codefresh repo but this seems to be make based, not terraform. So it is not clear how this would be applied using gitops. So I come into the same problem as with the helm chart above.

Does anyone have information about how to do these programmatically? Is just doesn’t seem correct to have these be done by hand.

@Erik Osterman (Cloud Posse) had some great results in my initial tests with go-task… here’s a link to my 101 walk through experience. https://bit.ly/363K7AC. thanks for the recommendation!

Improving Local Development Workflow With Go Task

Workflow Tooling Development workflow, especially outside of a full-fledged IDE, is often a disjointed affair. DevOps oriented workflows that often combine cli tools such as terraform, PowerShell, bash, and more all provide more complexity to getting up to speed and productive. Currently, there is a variety of frameworks to solve this problem. The “gold standard” most are familiar with in the open-source community would be Make. Considering Cross-Platform Tooling This is not an exhaustive list, it’s focused more on my journey, not saying that your workflow is wrong.

gotask is very similar to variant (v1 not v2)

sheldonh avatar
sheldonh

I thought it served a different purpose?

I did try variant 2. What I didn’t find was it being as intuitive. When we discussed I think you said the goal wasn’t necessarily to replace Make/InvokeBuild but instead to provide a common grounds for cli interfaces?

If so would like to hear more sometime

bradym avatar

Erik Osterman (Cloud Posse) avatar

Variant serves exactly the same purpose as gotask :-)

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

Starting with gotask is great though, then once that clicks variant and variant2 are more advanced tools that do the same thing

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

Variant1 is yaml based like gotask and variant2 is a complete rewrite that uses HCL

sheldonh avatar
sheldonh

Okay I guess I got confused. In our last thread on this it seemed that the conclusion was that variant to wasn’t meant to replace things like make files…. Only be a common interface for launching those. I did actually try variant too and experiment with it but it didn’t fit my needs. Are you saying that in the future you may replace make files and local scripts with variant files?

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

Gotask can call makefiles too :-) that was just an example. Let’s say you have a bunch of invoke build scripts and makefiles and ansible scripts and terraform commands and helm commands and Helmfiles… you can stick all those in gotask

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

Just the same way you could stick them in variant

sheldonh avatar
sheldonh

Why wouldn’t I just put those commands in go task itself?

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

Exactly - you can or you cannot - up to you

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

It’s a task runner

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

You can rewrite all those commands natively in gotask or you can just call those scripts or make targets - up to you

sheldonh avatar
sheldonh

More duct tape!

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

Variant is identical in purpose to gotask. The difference is that variant is on steroids. It might not become evident until you try both

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

Here is an example in variant 1 yaml

This helps call the commands to setup or upgrade tiller

sheldonh avatar
sheldonh

I mentioned I did try variant2. I’ve had exposure to both of them. I don’t have the use case of combining multiple task runners like make files plus wanting to wrap those up. I just want one interface. Sounds like a misunderstood what you were saying. I’ll definitely keep my eye on variant2 and revaluate for more complex scenarios in the future.

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

Variant can be invoked by running the “variant” command just like the “gotask” command, but it also supports #! style - which is where it becomes so cool.

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

Ya we want one interface - exactly

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

So I totally missed the mark then in explanation I gave you the first time month ago :-)

bradym avatar
bradym

I think the makefile example Erik makes is that you could wrap an existing makefile and add additional stuff and then end up with a single way to interact with all of it.

The benefit there would be getting to a single interface more quickly. Then when you have time you can refactor to just do what the makefile does in your variant yaml/hcl.

Interesting to see this. I haven’t thought about unikernels since doing a show on them with the IncludeOS folks. https://packetpushers.net/podcast/datanauts-114-unikernels-includeos/

Datanauts 114: Unikernels And IncludeOS - Packet Pushers attachment image

The Datanauts talk unikernels and IncludeOS with guest Per Buer. We learn how unikernels differ from a traditional OS, advantages & tradeoffs, & use cases

Adding a 2014 post I wrote on the same topic that has some additional links and thoughts https://articles.microservices.com/after-docker-unikernels-and-immutable-infrastructure-93d5a91c849e
