Question

Deploying the pgvector docker image fails

Posted on March 16, 2024
Docker PostgreSQL
Asked by Aron Weiler

Whenever I attempt to deploy the pgvector/pgvector:pg16 docker image, it fails to start. This does not happen when I deploy this in other environments- including locally using docker-compose.

Some info on pgvector docker image: https://github.com/pgvector/pgvector?tab=readme-ov-file#docker

Other things to note:

Deploy logs for the image contain only a single entry:
- [2024-03-16 08:14:25] ls: cannot access '/docker-entrypoint-initdb.d/': Invalid argument
Setting up a script (creating an image from the pgvector/pgvector:pg16 image with my own Dockerfile) to run a loop using pg_isready just spins forever, always returning false.

Any help would be appreciated… here is the relevant part of my app spec:

services:
- internal_ports:
  - 5432
  image:
    registry: pgvector
    registry_type: DOCKER_HUB
    repository: pgvector
    tag: pg16
  instance_count: 1
  instance_size_slug: professional-s
  name: pgvector

Hopefully someone else knows what’s going on here, and can help me out!

Hey!

I just tried deploying that Docker image and it seems to be working as expected as long as I set the POSTGRES_PASSWORD env variable:

Can you confirm if you’ve setup all of the required env variables by the pgvector Docker image?

Best,
