Error in GitHub actions when running the timescaledb-ha:pg16 docker image in testcontainers-go

[morris-kelly]

In the last few hours, I've started getting failing tests in GitHub actions with the following logs:

This can be reproduced by running this test in a CI pipeline

package main

import (
	"context"
	"testing"

	"github.com/testcontainers/testcontainers-go"
	"github.com/testcontainers/testcontainers-go/modules/postgres"
	"github.com/testcontainers/testcontainers-go/wait"
)

func TestTimescaleIntegration(t *testing.T) {
	dbUser := "postgres"
	dbPassword := "postgres"
	dbName := "postgres"

	_, err := postgres.RunContainer(context.TODO(),
		testcontainers.WithImage("timescale/timescaledb-ha:pg16"),
		postgres.WithDatabase(dbName),
		postgres.WithUsername(dbUser),
		postgres.WithPassword(dbPassword),
		testcontainers.WithWaitStrategy(
			wait.ForLog("database system is ready to accept connections").WithOccurrence(2)),
	)
	if err != nil {
		t.Fatal(err)
	}
}

I have had the exact same error with timescale/timescaledb-ha:pg15 and timescale/timescaledb-ha:pg16.3-ts2.15.2

Changing the image to testcontainers.WithImage("timescale/timescaledb:latest-pg16") enables the test to pass, which suggests that this is an issue with the -ha image.

Running with timescale/timescaledb-ha:pg16.3-ts2.15.1 pinned passes the tests also.

Running the failing images locally also works, this issue is only in GitHub actions.

We've also had this exact same issue today with our CI pipeline, which is using timescale/timescaledb-ha:pg14-all.

For now we've pinned to pg14.12-ts2.15.1-all.

Same issue here with timescale/timescaledb-ha:pg16.

It's working for me using the environment variable -e NO_TS_TUNE=true

docker run -d --name timescaledb -p 5433:5432 -e NO_TS_TUNE=true -e POSTGRES_PASSWORD=postgres timescale/timescaledb-ha:pg16

The issue is related to this script only docker-entrypoint-initdb.d/001_timescaledb_tune.sh

[us77ipis]

For me it is working now again with timescale/timescaledb-ha:pg16 too.
