KenCochrane··on Kargo, a multi-stage application lifecycle orchestrator
Hey Nick, it has been to long, I hope you are doing well. :)

I think they are similar but a little different. From Dagger's website "Dagger is a programmable CI/CD engine that runs your pipelines in containers" Kargo is a tool that works with your existing CI and CD (Argo CD) to help promote your code from one stage (Dev, UAT, QA, Prod, etc) to the next.

Kargo has native support for Argo CD today, but one of it's goals is to be agnostic and could probably work with Dagger or other tools in the future.

KenCochrane··on How we got our AWS bill to around 2% of revenue
Maybe I missed something, but how do you handle the fact that your nginx server is a single point of failure? If that goes down, traffic can’t get to your web servers.

Do you have more than one, and DNS load balance, or do you just live with the risk?

One of the main reasons why I use an ALB/ELB is so that I don’t have that SPOF. If you found a way around that, please share, I would love to know, so I can save some money :)

KenCochrane··on DigitalOcean Introduces Kubernetes Product
Too bad they didn't list the pricing, it would be nice to know how much it will cost, once released.
KenCochrane··on Ask HN: What's a side project you built to make money that hasn't?
That's pretty cool, I have been thinking of building something similar, but for Python. How hard is it to add new languages?

What is the tech stack?

Does it cost much to keep it running?

KenCochrane··on Running 1000 containers in Docker Swarm
Have you looked at Docker for AWS yet? https://www.docker.com/aws

It will setup your swarm, which uses auto scaling groups for the worker nodes. You can then configure the auto scaling groups how ever you want, to scale based on your cloudwatch metrics, etc.

There is also a Docker for GCP product in beta. https://beta.docker.com but I don't know how auto scaling works for it.

Disclaimer: I work at Docker on the Docker for AWS product.

KenCochrane··on Ask HN: What style for an image-resizing service?
This project looks pretty popular and they are using a URL based API, maybe you can copy their URL structure.

KenCochrane··on Ask HN: What style for an image-resizing service?
> I'm supporting images that end in .jpg, .png, or .gif. So currently I know that anything after the extension is parameters.

How do you know that is the extension and not a directory with a .jpg in the name? It is too complicated to convert to your URL scheme.

For me the URL based solution isn't quicker to type since I have to think too much. Also, how often is this going to be typed by hand verse scripted anyway? It will be easier to script if the URL is the same and only the GET Params change.

I prefer the get parameters, it is more obvious.

Another option that isn't as clean, but I have seen before is to Base64 encode the image URL. You wouldn't be able to easily type but you could keep your URL scheme, and still possible to script.

KenCochrane··on Hackers Tear Apart Trend Micro, Find 200 Vulnerabilities In 6 Months
It doesn't mention this in the article, but I assume they got paid by Trend Micro for their work? Bug bounties, etc. If so, I wonder how much they made?

KenCochrane··on I gave commit rights to someone I didn't know
What a small world, I worked with Greg at CashStar where he started the fork of django-money. I still remember the conversation we had in a meeting if we should fork the project or push our PR upstream to fix the issues we found. I'm glad our upstream PR started a trend to keep the library going. This is why I like open source, when you no longer need something you can hand it off to someone else who can take over, and let the code live on.
KenCochrane··on AWS Application Load Balancer
I wouldn't consider this a full haproxy/nginx replacement just yet. It doesn't support host based routing, so you would need a different ALB for each host in order to get the same thing you would get with haproxy/nginx.
KenCochrane··on Confirmed: Walmart buys Jet.com for $3B in cash
Jet.com ran a contest where they gave 100,000 shares as the top prize for the most signup referrals. This Guy is probably one happy guy right now. He spent $18k and the value of those stocks are probably worth in the millions.

KenCochrane··on Docker Betas for AWS, Azure, Mac, and Windows
You would be surprised how many people didn't see it in their spam folder. Hence the reason why I mentioned it. :)

Not sure what you mean about no message telling me to go get the bits today. There was no email saying that docker for mac/windows was made public, it was announced during the keynote at DockerCon (this morning), and a blog post went out.

Before we made it public, everyone who had signed up for the beta had an invite sent to them, and there was no one left in the queue.

KenCochrane··on Docker Betas for AWS, Azure, Mac, and Windows
Check your spam folder, some of the email from the last private beta went in people's spam folder, so they never saw them. Either way it doesn't matter anymore since Docker for Mac and Windows is now public to use without the need of a code.
KenCochrane··on Docker Betas for AWS, Azure, Mac, and Windows
Yup, try it out, and let us know if you have any issues, or ideas on how to make it better.

You can still use the CLI, there is nothing stopping you.
KenCochrane··on Docker 1.12: Now with Built-In Orchestration
Sorry for the issue, we are looking at fixing it.
KenCochrane··on Docker Betas for AWS, Azure, Mac, and Windows
It happened to me for a brief second, and it is fixed now, are you still seeing an issue?
KenCochrane··on Docker Betas for AWS, Azure, Mac, and Windows
Hello, I'm a developer on this project.

Our goal for this project was to keep it as simple as possible. We tried to only use standard AWS features (CloudFormation, EC2, Autoscaling groups, VPC, ELB, etc) and we are using Docker 1.12 out of the box, with no changes.

All of the scheduling is handled in the docker engine itself, so we didn't need to add anything outside of that.

This version is pretty much an MVP, and we hope that the beta testers will help us test it out, and guide the future direction of the project.

The name of the company is Tutum, not Tatum, maybe that will help your search results.

KenCochrane··on Bcachefs – A general purpose COW filesystem
Sounds like a really cool alternative to aufs, would love to see a Docker storage driver added to support this, once stable. https://docs.docker.com/reference/commandline/daemon/#daemon...

Any chance this might get added to the mainline kernel? aufs was never able to get merged in. OverlayFS was merged in, but IMHO isn't as good as aufs.

KenCochrane··on AWS S3 Having Problems Again? (Monday 12PM Pacific)
From Amazon:

"Hello, We have just become aware of EC2 network connectivity issues in the US-EAST-1 region. The impact of this issue is loss of network connectivity to EC2 instances in US-EAST-1. The AWS support and engineering teams are actively working on bringing closure to this issue. I will share additional information as soon as I learn more about this issue."
