default docker compose up : unable to connect to para after 10 tries #325

Closed alkuma closed 2 years ago

alkuma commented 2 years ago

I am trying out scoold on my redhat 8 laptop.

Here's what I did:

https://github.com/Erudika/scoold/blob/master/README.md#docker is the source of the instructions

  1. docker pull erudikaltd/scoold:latest_stable fetches me the image
  2. create a new directory called ~/scoold and copied https://github.com/Erudika/scoold/blob/master/docker-compose.yml into it with the same name
  3. touch para-application.conf scoold-application.conf so I have these two blank files in the ~/scoold/ directory
  4. finally ran docker compose up

I get

Which tells me that scoold is not able to connect to para.

Is para up?

  1. loading http://localhost:8080/v1 on the browser gives me
{
  "info" : "Para - the backend for busy developers.",
  "version" : "1.46.2"
}
  1. ssh to the container and running a wget via http://para:8080/v1 also gives me the same

So para is up and is accessible within the container via http://para:8080

scoold is up as well, on http://localhost:8000/ and accessible via the browser.

So, I don't know why scoold can't connect to para when I can connect to it via both the browser as well as within the container via wget

I followed the README to the letter, so what's wrong with the instructions or my interpretation of the instructions?

There is a similar issue that got resolved by updating the README, but it's the updated documentation that's being followed - https://github.com/Erudika/scoold/issues/180 from two years ago

Thanks in advance

You are not following the guide closely. You don't have to pull the images manually. Just do this:

  1. First, create a new directory and copy docker-compose.yml.
  2. Create the two configuration files in the same directory (both files can be left blank for now): 
    $ touch para-application.conf scoold-application.conf
  3. $ docker compose up
ShenQingchuan commented 1 year ago

I did exactly what the instruction described, except I commented out the expose 8080:8080 of Para, because the 8080 port is already taken by another application. But I didn't resolve the same issue above.

@alkuma Did you resolve this after that? I'd be so appreciated about for your provided information.

albogdano commented 1 year ago

@ShenQingchuan If you want to run Para on a different port, you will have to modify the docker-compose.yml file and change 8080:8080 to 8081:8081, for example. Then add this to your Para configuration file:

para.port = 8081

Then also update the Scoold configuration to connect to Para on 8081 with scoold.para_endpoint = "http://localhost:8081" and restart the two containers.

So I see, I think we may update the docker-compose.yml too.

There's a config argument passing to JAVA_OPTS: -Dscoold.para_endpoint=http://para:8080

is this argument still useful for my situation?

I found myself not be able to create that secret key, even not be able to re-run the process, because no matter how many times I docker-compose down and docker-compose up, it always shows that [WARN ] Secret key appears to be invalid. Make sure you call 'signIn()' first.

albogdano commented 1 year ago

@ShenQingchuan You may have to delete all volumes for both Para and Scoold containers and start over. I see that Para is still running on 8080 even though you changed the port in para-application.conf.

Also change -Dscoold.para_endpoint=http://para:7676
