I am getting this in the logs on Meltano version 1.34.1

[2020-05-27 17:43:09,618|W|MainThread|root] You must update Meltano to get new plugins updates.

[2020-05-27 17:43:09,787|I|MainThread|meltano.cli.ui] All workers started.

Is there a way to update to the correct version?

meltano upgrade

I believe

I have tried that. I get this in the update:

System database up-to-date.

1.34.1 looks like the latest version. Sounds like something internal

@matthew_trinkle Hmm, that’s not right. The error message implies that in your meltano installation, this line: https://gitlab.com/meltano/meltano/-/blob/master/src/meltano/core/plugin_discovery_service.py#L39 still says

10

, rather than

11

, despite that having been changed in v1.34.0 (and v1.34.1). Can you check if that’s actually the case on your file system?

where is meltano core located in the docker?

@matthew_trinkle Ah, you're using the Docker image from https://hub.docker.com/r/meltano/meltano?

I believe so

@matthew_trinkle Can you show me the output of

docker run meltano/meltano --version

?

1.32.1, but inside docker

meltano --version

says 1.34.1

@matthew_trinkle All right, I think the issue is that

meltano upgrade

is not actually supported when using the Docker installation method (which I didn't fully realize until now and isn't documented), because while you can make changes inside a Docker container, the Docker image itself is a snapshot and won't be updated until you actually pull a new version of the image. So if you're using Meltano with Docker, the way to update would be to run

docker pull meltano/meltano

and to then recreate your container. If you're using

docker-compose

, it'd be even easier:

docker-compose pull meltano && docker-compose up -d meltano

okay thanks!

@matthew_trinkle Let me know if that works!

I was just testing this out on my local, but I think I am switching to something else in prod

@matthew_trinkle "something else" as in not-Meltano, or as in, a different installation method? 🙂 In the former case, I'd love to know why Meltano turned out to ultimately not be the right fit for your use case right now!

sorry, installation method

@matthew_trinkle Cool, let me know if you run into any more trouble 🙂

My company uses Convox

@matthew_trinkle Ah, cool! I plan to look into making it easier to deploy Meltano onto K8s (https://gitlab.com/meltano/meltano/-/issues/2014), so any feedback based on your experience would be appreciated in that issue!

@douwe_maan Will do!
