What a series of unfortunate events for Docker in 2019. In what appeared to be a massive talent flush due to what looks like a potential earnings miss, the Great Docker Culling of 2019 happened. Docker appears to have laid off the vast majority of its well-known talent. Andrea Luzzardi, Sam Alba, and Gareth Rushgrove are among a slew of recent Docker layoffs discussed in this newsletter earlier this year. According to one source teams were, “killed,” and Docker, “missed their number, and by a lot.”
Fast forward to Friday night on the US east coast (like we weren’t going to notice?!?). Many people (myself included) received an e-mail from Docker about a Docker Hub breach impacting at least 190,000 accounts. According to the e-mail, “Data includes usernames and hashed passwords… as well as Github and Bitbucket tokens for Docker autobuilds.” Audit any Docker Hub tokens right now. Docker also, “revoked GitHub tokens and access keys. This means your autobuilds will fail.” Nothing like a page on a weekend because Docker broke your builds. Check your Docker Hub Linked Accounts and re-link them. You’ll then likely have to do a weird do-si-do in the Build config of one of your image pages to get everything working as is.
This Docker Hub breach is a significant breach. If any of the tokens of any of the common base images had been compromised — packages like Alpine, busybox, Node.JS, or any of the major databases — these could have easily permeated into the wild with little or no knowledge. From my point of view, the only way to be sure you’re not affected is to somehow verify with the image provider that their account has been cleaned up and redeploy all your containers. Cleaned up as directed by Docker (note the URL, “success”). Why? Because it’s likely some upstream used Docker Hub even if you didn’t. In other words, “Nuke the entire site from orbit. It’s the only way to be sure.” Yes, it’s that bad until it’s confirmed otherwise.
What a Docker freaking mess we’re in. At the risk of being extra petty, I can’t help but mention I started using Quay when I joined Red Hat and I’m pretty happy with it. It’s a container registry, not an Alexander Wang piece. Quay is not perfect but, I’m not expecting a whole lot here. It looks like I’ll be moving more images off Docker Hub in the future.

DNS over HTTPS is coming whether ISPs and governments like it or not — Encrypting your DNS queries in the payload of an HTTPS packet means that countries and companies can’t as easily hijack DNS to control internet access or to monitor employee activity. Conversely, blocking known bad DNS entries (sinkhole) and using DNS query logs to hunt for indicators of compromise are common security measures. This becomes a MUCH harder problem.

DevOps’ish Tweet of the Week
On the Docker breach: Even if your company doesn't rely on Docker Hub for production, if a developer in your org enabled auto builds and linked to GitHub via oauth for a personal project, when that oauth token is compromised, _all_ repos on GH they had access to are vulnerable.— Kenn White (@kennwhite) April 27, 2019
