Docker Compose

Description

I'm running Speedtest Tracker (latest image) through docker compose inside of Komodo, in case that's relevant. There's nothing going on in the logs.

I'm able to do manual speedtests without issue, but I can't seem to schedule anything via the environment variable.

Relevant line from docker-compose.yml: SPEEDTEST_SCHEDULE:5 * * * *
Relevant line from docker compose config: SPEEDTEST_SCHEDULE:5 * * * *: null

I'm a Docker novice and even newer to Speedtest Tracker, but this looks to me like it's not understanding the environment variable somehow. Did I do something wrong?

Anything else?

There's a small issue with your environment variable: if the value contains special characters like * (common in cron expressions), it must be enclosed in quotes. Without quotes, YAML can misinterpret the line—especially in Docker Compose—leading to unexpected behavior.

To fix it, wrap the cron expression in double quotes like this:

SPEEDTEST_SCHEDULE: "5 * * * *"

This ensures that SPEEDTEST_SCHEDULE is correctly recognized as the key and "5 * * * *" as its string value.

I'd previously tried that (without the space) and it didn't work, but in looking at my docker-compose.yml again to go try it out with the space, I noticed something even sillier... I was using a colon instead of an equals sign like everything else. SPEEDTEST_SCHEDULE="5 * * * *" works perfectly fine. I feel really dumb, and I really appreciate your response because it prompted me to look at my syntax differently.

Compose can handle both colon and equals signs 😉. Happy it all works now!
