Unable to run railway run

In railway-cli version railwayapp 3.3.1 in a linked project and service, when I try to run a railway run command it just run locally. My project is a Docker project with a different docker file that the default one. It does not matter if a run within a subshell (railway shell) or not. I already tried docker commands, unix commands and web server commands (rails) and nothing works. Am I doing something wrong?

no you're not doing anything wrong railway run only runs commands locally, it first pulls the environment variables from your railway service and then runs the given command locally with the service variables now available same with railway shell it is a local shell, just with the variables from the railway service added

Thank you Brody !. It is possible to run the command inside the Docker container??.

Brody•17mo ago

it is not, but tell me the command you want to run and maybe I can come up with a solution for you

nr•17mo ago

Sure!, I'm running a dockerized rails application. I'm looking to have a rails console, so the command for that usually is.

docker exec -it container_id rails console

docker exec -it container_id rails console

Brody•17mo ago

im not a ruby/rails dev so could you help me to understand what a rails console does/achieves?

nr•17mo ago

sure, rails console lets you interact with a rails application within the terminal

Brody•17mo ago

interact how like what is the ultimate end goal here

nr•17mo ago

Is a REPL

Brody•17mo ago

dont know what that is

nr•17mo ago

ok, so I'll give you an example

nr•17mo ago

This is an example of a repl in node.js https://www.digitalocean.com/community/tutorials/how-to-use-the-node-js-repl

How To Use the Node.js REPL | DigitalOcean

The Node.js Read-Eval-Print-Loop (REPL) is an interactive shell that processes Node.js expressions. The shell reads JavaScript code the user enters, evaluate…

is kind of similar in ruby but with the entire application loaded so you can execute ORM / database commands, explore the application and do troubleshooting basically you are interacting with your application with console

Brody•17mo ago

got it, but specifically what do you want to execute

nr•17mo ago

e.g. I want to re-send an email to a user that didn't receive the email. with rails console I can do something like.

docker exec -it container_id rails console

# The interactive console is open
> User.find_by(email: '[email protected]').send_welcome_email

docker exec -it container_id rails console

# The interactive console is open
> User.find_by(email: '[email protected]').send_welcome_email

yep, so you will need to do something like rails console but we don't let you SSH in yet (soon, as a former Rails dev, I understand the need to)

nr•17mo ago

Hi Angelo, thank you. That would be awesome.

Brody•17mo ago

for now i think you would need to implement something like that in an api endpoint

angelo•17mo ago

that or under /admin routes

nr•17mo ago

Is there a way of execute rake tasks? or bash scripts?

angelo•17mo ago

rake on init but no, you should think as deploys as final cuts of your code

nr•17mo ago

I understand, that's the way. I'm exploring what kind of things I can do developers can make mistakes, and I would like to understand if there is a way to troubleshoot cases with exceptions.

angelo•17mo ago

I get it but jumping into the running state of the app atm isn't how we currently support the debugging loop

angelo•17mo ago

anyway hope this helps and you can upvote a similiar feature request over at https://feedback.railway.app

sure, you guys are doing an amazing job, would be good if you can release that soon I'll vote for sure so basically railway run is not working in a Dockerized application atm.

Brody•17mo ago

as stated above, railway run is for running commands locally only

nr•17mo ago

do you have documentation with some examples? just to understand better the use cases

Brody•17mo ago

from railway --help

run          Run a local command using variables from the active environment
shell        Open a local subshell with Railway variables available

run          Run a local command using variables from the active environment
shell        Open a local subshell with Railway variables available

the docs talk about it a bit more https://docs.railway.app/develop/cli#local-development

nr•17mo ago

I'll run node and rails applications, dockerized and non dockerized, so would be good to have a better understanding of that.

Brody•17mo ago

thats about all the information i have on the matter

nr•17mo ago

ok, I think I can run rails console pointing into the production database with that. I don't need to jump into the docker container. So that can help. I'll let you know If I have succeed with that.

Brody•17mo ago

yeah that should be do-able for database related actions

nr•17mo ago

Ok, I was able to run rails console with railway executing the following command

railway run rails console -e production

railway run rails console -e production

Hope this can help someone else.
