This looks to be the beginning of the "extinguish" step from Google. They've executed the embrace, extend, extinguish playbook to a T with Docker.

The top contributors to containerd are all from Docker.

jrs954• 8 years ago

Google is just one of many organizations involved in Kubernetes. If this has anything to do with embrace, extend, extinguish, it's to prevent Docker as a company from attempting to do anything like that to Kubernetes.

Edit: I take that last part back. This seems to ensure that neither party can easily fuck each other over, and that's a good thing.

To be fair, Kubernetes was a big competitor to Docker Swarm and Docker’s own Cloud, which kind of lost the battle. One has to wonder what would have happened if Google did not build Kubernetes, which heavily embraced Docker.

Sometimes it’s not all that black and white, Google seems to mainly be afraid of one competitor becoming too powerful and losing control. Android vs iPhone being another example.

? Per the announcement, Docker Engine is also built on containerd.

jrs954• 8 years ago

Seems like more of the usual FUD that shows up on literally every post about Kubernetes regardless of the context.

waffle_ss• 8 years ago

But Docker created containerd to begin with...?

It sure looks like there was a plan to completely eliminate Docker and replace it with CRI-O and it looks like Docker Inc. responded to that plan by creating containerd so they could maintain some level of relevance. So yes, Docker can stay involved as long as they deliver what k8s wants, but k8s is clearly in the driver's seat now.

True. Also:

- email. Keeping your own server unblocked by Gmail is a loosing battle.

- Web. Google AMP. Use it or get lost in search results.

- Android. Try make a phone with open source Android without Google apps and licensing.

This is great. Anyone know what Google's plans are when it comes to rolling this out on GKE?

thesandlord• 8 years ago

Containerd 1.1 works with Kubernetes 1.10 and above

Kubernetes 1.10 just came out on GKE, so I assume it should work today!

https://cloudplatform.googleblog.com/2018/05/Google-Kubernet...

(Note: I haven't personally tried this out. I also work for GCP)

lobster_johnson2• 8 years ago

I don't see it mentioned in the GKE release notes, so I assume there's no option to enable it yet.

erikb• 8 years ago

The fact that A is tested to work with B doesn't necessarily mean that a packaged service will provide both A and B, though.

Random-Liu• 8 years ago

Disclaimer: I work in Google, wrote the blog post.

We are working on rolling out containerd 1.1 to GKE alpha cluster. If everything goes as expected, it will be available in GKE alpha cluster soon.

simonebrunozzi• 8 years ago

For the few that are not familiar with the acronym GA, that means General Availability.

Typically this means the removal of a "beta" tag, and a general expectation of a service that is supposed to be available for most of the time, and not have significant security issues or bugs.

In some cases a GA release is accompanied by an SLA (Service Level Agreement), e.g. uptime of 99.9% measured monthly.

I know, it sounds obvious. You might be tempted to downvote me :)

And yet, when I was a tech evangelist and later a CTO, I realized the importance of being as clear as possible when explaining things (including titles). You would be surprised at how many people got lost with even the most basic acronym.

rdsubhas• 8 years ago

Modern GA literally means generally available, as in:

that service seems to be down!
huh, its generally available...

alpb• 8 years ago

In Kubernetes terms (and the context of this feature), GA means stability (rather than SLA). When a Kubernetes feature is in alpha/beta, it may go through breaking changes between releases. For this feature, it means it is no longer considered an experiment and is recommended for production use.

For Kubernetes API, alpha/beta process and the deprecation policy is documented here: https://kubernetes.io/docs/reference/using-api/deprecation-p...

How about something for the few that are not familiar with 'containerd' ?

takeda• 8 years ago

My understanding is that it replaces docker for running the containers.

nineteen999• 8 years ago

I asked myself the same question a little while back, and landed here:

https://blog.docker.com/2017/08/what-is-containerd-runtime/

Although I ended up coming out of it with more acronyms in hand, and perhaps only slightly less confusion than when I went into it.

diamondo25• 8 years ago

Thanks! Although I have seen GA before (including the words General Availability) on the MySQL download page, I now only thought of Google Analytics, and then Google Apps (more related to the topic).

esseti3• 8 years ago

I'm familiar with K8 and docker, but not with Containerd. does this means that now K8 supports containers that are not created with docker but rather with Containerd ? is that correcet? if so, what's the benefit? i miss some background here.

chupasaurus• 8 years ago

Docker daemon is running on top of containerd, so it was an additional layer which could be avoided and that's exactly what was done. The benefit is less latency and resource consumption.

esseti3• 8 years ago

so, do I've to create the container in a diffrent fashion or will be k8s doing all the stripping?

neic2• 8 years ago

Do you mean K8s as an abbreviation for Kubernetes, or am I again out of the loop with some new tech in this fast moving field?

sewer_bird• 8 years ago

Indeed, K8s is a numeronym[0] for K(ubernete)s.

AWS ECS was GA in 2015. With load balancing, autoscaling, health and update management. Just saying :)

auslander6• 8 years ago

Hmm ... Does Google has its own troll factory? Whenever I say something against it, downvotes come, always without replies.

asey• 8 years ago

It's because your comment belies your understanding of the article and the nature of the announcement. It makes no sense to compare AWS ECS in it's entirety to the rollout of containerd. The correct comparison in your case would be with Kubernetes Engine against ECS.
