Self-Hosted Version

26.1.0

CPU Architecture

x86_64

Docker Version

29.1.5

Docker Compose Version

5.0.1

Machine Specification

• My system meets the minimum system requirements of Sentry

Installation Type

Fresh install

Steps to Reproduce

Fresh Debian 13.3.0 VM running on 4 cores, 16 GB RAM (host is UGreen 4800 Plus NAS running latest UGOS - 6 cores and 40 GB RAM). When running install.sh I get this error:

▶ Bootstrapping and migrating Snuba ...
time="2026-01-19T23:20:25+02:00" level=warning msg="No services to build"

-> ./install.sh:main:40
--> install/bootstrap-snuba.sh:source:4

install/error-handling.sh: line 81: /usr/bin/docker: Argument list too long

This is the second time I'm going through the process - same error.

I ran the install script for a second time, and it then successfully completed. However, web docker container never came up, although all of the others did. Various snuba processes 100% utilised all 4 CPU cores for over 10 minutes and the VM became almost unresponsive due to high load. I eventually had to shut down it down.

Expected Result

I expected the install process to work, all containers to come up, and the CPU to be mostly idle.

Actual Result

Event ID

No response

I've just tried a clean install on a new VM (on the UGreen) running Ubuntu 24.04.3 LTS and got a similar error:

I fixed this (on my Ubuntu VM) by:

docker pull confluentinc/cp-kafka:7.7.7

then running the installer again. The installation now completes successfully. There is still a long lag of around 5 minutes when the containers come up for the first time, with high system load and 100% usage across all CPU cores, then everything settles down and I have a log in page (which doesn't work - "CSRF Validation Failed" - but that's another matter).

CSRF verification failed is here: https://develop.sentry.dev/self-hosted/troubleshooting/sentry/#csrf-verification-failed

But I'm really curious that this is what you got

 Container sentry-self-hosted-kafka-1 Error response from daemon: No such image: confluentinc/cp-kafka:7.6.6
 Container sentry-self-hosted-redis-1 Error response from daemon: No such image: redis:6.2.20-alpine
Error response from daemon: No such image: redis:6.2.20-alpine

It must not happen, since public Docker image must never be deleted https://hub.docker.com/layers/library/redis/6.2.20-alpine/images/sha256-0e2e853efd5c253bacaa15e7e9f10c467153d53b3d2fab62c5de6bdd60cd38d2, the same goes for the Kafka image.

Maybe Docker hub was having an issue, or I was being rate limited somehow? I only saw the redis image error once, and doing docker pull confluentinc/cp-kafka:7.7.7 worked when I ran it manually. Happy to have this closed if no-one else gets this issue, as I was able to run the install.
