Webodm: Support docker swarm deployments

[bubthegreat]

How did you install WebODM? (Docker, natively, ...)?

Git clone, and docker-compose up -d - that works fine

What's your browser and operating system? (Copy/paste the output of https://www.whatismybrowser.com/)

Not a browser or platform issue

What is the problem?

Would like ODM to be deployable to a swarm stack

What should be the expected behavior?

single command to deploy a scalable stack via docker stack deploy, i.e.:
docker stack deploy -c docker-compose.yml webodm

How can we reproduce this? (What steps did you do to trigger the problem? What parameters are you using for processing? If possible please include a copy of your dataset uploaded on Google Drive or Dropbox. Be detailed)

Try to deploy via docker stack deploy and it'll fail, because it's not designed for a stack deployment. Stack deployment would preferably be in a later compose version (3.x+ rather than early 2.x - there are a lot of improvements since then)

Hey @bubthegreat, that would be a cool addition! Would you have an interest in contributing to it?

[bubthegreat]

Absolutely! I'll pull the repo and see what I need to do to get it to
work. Will post questions here unless theres a better place for it.

That's fantastic! :+1: This thread is fine for questions.

[bubthegreat]

Allright - initial questions:

1. Is there an entrypoint for dynamic addition of nodeodm nodes, or is that currently done manually? It looks like we're statically defining the hostname for the initial (node-odm-1) in the start script - this might make it challenging to scale workers if they don't have an automated way of joining a cluster. Is there a join key that we create somewhere that we can define and share across all of them so we can dynamically add a new node if we scale them, or is this just done manually right now?
2. Any reasons we're defining the entrypoint in the compose file that I should be aware of, or is that something we can move to the image and let folks override the "start"

[pierotofy]

1. It's currently done via docker-compose (1 node max, no possibility to add more).
2. Assuming you are referring to the webodm_webapp image, we use an entrypoint in docker-compose because we spawn two containers, one is the actual webapp, the other is a background worker. There's probably other ways to set that up (have two separate images with different entrypoints?) I'm guessing.

[bubthegreat]

Looks like I'm going to have a baby instead and probably won't be able to
get to this for a while, but if nobody else picks it up I'll jump back on
it as my time frees up.

Congrats! I can understand the shift in priorities :smile: I'll leave this open for future development.

Hello,

I will start tackling this issue and keep you updated guys.

Thanks,
Ahmed Hefnawi

[hefnawi]

Still working my way slowly through webODM and in parallel working on the docker stack yaml file, however, I will just ask questions here if you don't mind whenever I get stuck =)

[pierotofy]

Of course @hefnawi , thanks for the update! :+1: Let us know if you have questions.

[Ghost7K]

@hefnawi i also tried to deploy it to a stack, and now that i found this thread i was wondering if you had success with Docker 3x Swarm deploay. Greetings

[bubthegreat]

Current setup does not lend it self to swarm deployment, no - the dockerfiles would need to be rewritten for swarm/kubernetes configs.

[antonyharfield]

I'm interested in deploying to Kubernetes and can help out translating files if needed -- has any work been started on this already?

[dimm0]

Working ok for us in kubernetes: https://gitlab.nautilus.optiputer.net/prp/webodm
I found that there's a horizontally scalable version now. But still no support for kubernetes
