Issue Deploying a Python Application on Railway
Project ID: f2fafb89-464a-475d-8a88-80b715a91259.
Hello everyone,
I'm having trouble deploying my Python application on Railway, and I was wondering if someone could help me resolve a specific error. The error I'm facing is as follows:
"Container failed to start. We failed to create a container for this image."
I'm using Railway to deploy my application with a Dockerfile and a Procfile. Could anyone provide some guidance on what might be causing this issue or how to resolve it? I greatly appreciate any help you can offer.
Thank you in advance!

f2fafb89-464a-475d-8a88-80b715a91259your dockerfile isnt doing anything nixpacks cant do, try removing the dockerfile
Hi there, Brody! Thanks for your prompt response. I've removed the Dockerfile as you suggested since Nixpacks can handle the build process. However, now I'm encountering the following error after removing the Dockerfile.
ive been here a long time and i have seen a lot of builds fail, but i have never seen railway say to install docker
to be clear, thats railway telling itself to install docker
The error is seen when the container fails to start on startup. Have you checked that your start command is correct and works locally? Is gunicorn installed?
ive seen the error when gunicorn isnt installed this is nothing like that lol
Sorry I was refering to the first error
ah gotcha, but uh i think theres now a bigger problem π€£
Builds look all good on our end. Can you try deploying again?
Should I try it with the Dockerfile added to the project again?
nope
In that case, it continues to give me the same error
how did you trigger the new deploy?
I'm simply changing a variable, and then I add it back to make a redeploy.
for future ref, you can also use this
fair enough
try using this https://bookmarklets.up.railway.app/service-redeploy/
It continues to give me the same error since I removed the Dockerfile.
that's not ideal, I'm confident this isn't anything you're doing wrong
can you try spinning up another project, that way your service will hopefully use a different builder
@Brody do you check pm ?
I have another website online that is not giving me any kind of issues.
um why
bfortuna, do you know tsh?
No :/
i saw you answering problems and i have one too, i am new , i was trying to contact you in pm
sorry for interrupting

open your own #βο½help thread
ok ty
I have this other website that is working wonderfully. Can I attach the link to this one?
Solution
yeah but can you try creating a new project to deploy this app
Okay
In these two deployments, the first one was done with the environment variables added, and the second one without adding them. In both cases, the Dockerfile is obviously not present.
same install docker issue?
In the one with the variables added in Railway, it's giving me the same error as with the Dockerfile.
show me the error
Okay, let me explain. I removed the environment variables PORT, PATH, and HOST from my project, and now the project is visible π
can you still show me the logs for that failed deployment

interesting
you dont need to set a PORT or HOST variable for gunicorn anyway?
but what where you setting those 3 variables to?
I don't even know how to thank you for taking the time to help me with my project. It's working practically everything. I only have one error left, but I think this one depends on me π
No, I don't need those variables; it seems it was a layer 8 error
I'm trying to use the session_id to create a cart for the user (it's a kind of Ecommerce website). I will still solve it on my own, but if you know about it, please let me know. Again, I thank you for helping me and giving me the most valuable thing, which is time.

fwiw, it was an issue with setting the PATH variable
and I'm sorry but I don't know about that, I'm not a python dev
No problem, thank you very much π
