Everyone repeats that alpine images are smaller. Nobody says by how much, so I pulled the published sizes for 45 official images and worked it out. Median ratio between and : 2.3x. Which is much less dramatic than the…
Storm took the line out. Power and LAN were fine, so it became an accidental audit. Kept working, no attention Media, books, photos. Anything reading local storage. Notes and documents syncing over the LAN. Recipes,…
Everything is in compose files, which are in git, so rebuilding the stack is straightforward. What I do not have is any backup of the data. The problem is that I do not have a clear picture of where the data is. Some…
I have a single machine running several services behind one reverse proxy, which handles certificates and routes by hostname. That works nicely for anything over HTTPS. I now want to reach a service over SSH on the same…
I moved a service into a container and mounted a directory from the host so the data survives restarts. The container starts and then fails with permission errors writing to that directory. If I make the host directory…
I understand that two containers do not have access to the same memory at the same time: the isolation there is clear enough. My question is about the handover. Memory is over provisioned on this host. If one container…
A service behind my reverse proxy insists on HTTPS with its own self signed certificate. The proxy terminates a proper certificate at the front and then fails when connecting to that backend, complaining about the…
Small API, Node 22, running under compose on a 2 GB Hetzner box next to postgres and caddy. Under any real traffic the api container dies: says . I set in compose specifically to protect postgres. RSS sits around 300 MB…
Plain docker build on an Apple Silicon laptop, pushed to a registry, then compose pull on an amd64 vps and the container exits immediately with exec format error. I have seen platform, buildx and just build on the…
Two months into the first thing I've had actually online. I ssh into a $5 box, , , and it works. Every tutorial past this point is CI pipelines, blue green, staging environments, terraform. Is what I'm doing an…
Solo dev. Twelve services split across two boxes, one compose file each, plus a pile of shell scripts for deploys and a failover procedure I have written down and never actually tested. Kubernetes is obviously out of…
Currently postgres 17 in compose next to the app, data on a mounted volume, to R2 nightly from a cron container. 8 GB and growing maybe 400 MB a month. Two person team, no ops person, we ship a lot. Someone on the team…
Single VPS, docker compose, caddy in front. Deploy is . Compose stops the old api container, starts the new one, and for roughly 30 45 seconds caddy returns 502 while the new one boots. It's an internal tool so nobody…
Twelve of us, everyone develops on Docker Desktop on Macs, and our CI pulls base images from Hub on more or less every build. Someone asked in standup whether we are technically in breach and nobody in the room knew the…
says 1.42 GB for a fairly ordinary Express + Prisma API. I build locally and push to a private registry over home internet, so every deploy is a coffee break. Dockerfile is basically: I know this is bad. I don't know…
Side project, 30 req/s at peak, mostly reads, one postgres, one node api, one worker, plus about 40 GB of user uploads sitting in R2. A CX22 is around 4.50 euro a month and I'd run everything on it with compose. Fly…
