It looks like it is a bug of latest version Google COS Google, Container-Optimized OS, 105-17412.156.30 LTS, Kernel: COS-5.15.120 Kubernetes: 1.25.5 Docker: 23.0.3 Family: cos-105-lts.

VM using older version has no issues.

---

Workaround

1. Create Dockerfile with command RUN chmod 777 /tmp
2. Shut down all affected container by docker-compose down
3. Remove all the unused images by docker image prune -a
4. Clear all the cache bu docker system prune
5. Turn on the containers by docker-compose up -d, it will rebuild all the needed image and set correct permission to /tmp.

docker-compose on Container Optimized OS (GCE) with access to GCR & GAR

For Docker Compose V2.0, please read the comment below.

Docker Compose V1.0

Since GCE's Container-Optimized OS do not include docker-compose by default. So, we need to use the official docker/compose image as a workaround. However, docker/compose cannot access GCR or GAR to pull private images. Therefore we have to create a custom docker-compose image which is authenticated to GCR / GAR.
