Bump airflow version to 1.10.10 #537
base: master
Are you sure you want to change the base?
Conversation
fix: #535
Hopefully we can see this merged. I opened an issue a couple days ago #536 But it seems like this repo is not maintained anymore. Simple fast forward PRs are not being merged. No new commits... |
Bump |
With airflow 1.10.10 release they also support a Production docker image. You can read about it in the official blog. I've been using it instead of this one. So far so good It would be nice if puckel keeped the docker-compose.yml files updated ( |
A production ready docker-compose with secret handling etc would be nice. |
@wittfabian , github.com/apache/airflow releases an official production ready image. This repo is no longer maintained (it seems)
|
Yeah, we use that too. Or how best to build on the base image to get your own configuration. User, SSL, connections, variables. Using the image is usually only half the battle, the difficult part is not described anywhere. |
I know what you mean. I deployed my stack in a single machine with an external db as a service to make the deployment as idempotent as possible (not holding Data or state but only functionality) Depending on your needs you might want one kind of deployment or another. For example, if you cannot afford spending a couple of months learning kubernetes, or if in a big team anyone should be knowledgeable of the deployment process I suggest some easier technology (docker compose or docker stack) If you need routing between several instances of the webserver and SSL you can use traefik. But if it's not open to the public, or running inside a VPN then SSL is only makeup. If you need to scale BIG then I suggest scaling horizontally adding templated Machines docker compose and a bunch of workers. But if you are in early stages you can get away with scaling vertically simply upping the Machine resources For sincing your dags there are options too, depending on how do you want your deployments done. There's people that:
In terms of local deployment it depends on the airflow version you are using . If you choose the stable 1.10.x you can get away with the pip version to run the whole thing. But if you run the 2.0 then it's best to run a small docker-compose stack, because web resources are not built and dependencies are not installed . So you see, there's lots of options (even more than I listed). It depends on what you want |
Since migrating to the official image is being discussed here I want to add some stuff I figured out today. First of all, here's a discussion on the official docker image with docker-compose examples: And here's what I had to do to migrate from puckel's image... Migration to official imageAnd in order to change from the puckel version to the official one, I had to...
I was also upgrading from 1.10 and had exceptions when accessing the web interface. It turned out NULL in the UPDATE dag

Hello. How were you able to run the official airflow image? I have made the pull and after that |
You can use a "init task". |
@KimchaC Works for me!
|
@athenawisdoms yes you can adjust the first line in the Makefile: |
Just for reference, we've also been using airflow by dividing it into two repositories of dags and the other one is for the docker-compose infra. |
@gnomeria Is there any resource on how to do that? |

Some of the steps are a bit manual too. And it lacks some security measures. For the webhook, I think you should do something like https://github.com/adnanh/webhook to run a git pull with a webhook token. Though it's been running fine for almost a year now with that😃 For the airflow-dag repo, it's a bit more straightforward, and it contains only a dag codes. It's also being structured with multiple folders and has some shared commons/modules with unit testing with |
