Moodle Docker Web Service working but can not be called from another docker container in the same ne-CodePudding

I am running a moodle docker container and one other container to call moodle web service function in a same network. I'm pretty sure I have set up the moodle properly because I can call moodle web service from postman. I am also aware i need to use the container alias of the running moodle container, which in this case is webserver. This is what i have tried

calling http://localhost:8000/webservice/rest/server.php?moodlewsrestformat=json&wstoken=fa4e7222df472b032ca9b4bd6d17595a&wsfunction=core_user_get_users&criteria[0][key]=id&criteria[0][value]=2 from Postman and it return the following response

                },
                {

                }
            ]
        }
    ],
    "warnings": []
}

but when i try calling the same API from the other container i get a 403 response status, i also tried calling the same API with curl inside the container using curl -v -g 'http://webserver/webservice/rest/server.php?wstoken=fa4e7222df472b032ca9b4bd6d17595a&moodlewsrestformat=json&wsfunction=core_user_get_users&criteria[0][key]=id&criteria[0][value]=2'

with result:

*   Trying 172.18.0.8:80...

so it is clearly connected but somehow still return 403 response, am i missing something? is there another moodle settings i have to tweak?

I am using moodle-docker with added

networks:
  default:
    name: network_name
    external: true

at the end of base.yml file so it could connect to the current project I'm working on which is a Node.js project that will call one of the web service on moodle. Here is the docker-compose.yml which relevant to this question

version: "3.7"
services:
  test:
    build: .
    env_file:
      - "./.env"
    ports:
      - 8085:8085
    networks:
      - network_name

networks:
  network_name:
    driver: bridge
    name: network_name

this is the result of calling docker logs of the moodle container

172.18.0.1 - - [22/Jun/2022:15:38:27  0000] "GET /webservice/rest/server.php?wstoken=fa4e7222df472b032ca9b4bd6d17595a&moodlewsrestformat=json&wsfunction=core_user_get_users&criteria[0][key]=id&criteria[0][value]=2 HTTP/1.1" 200 1464 "-" "PostmanRuntime/7.29.0"

This error doesn't make any sense to me because i already enabled the web service and the REST protocol on the site administration settings. I also tried to enable web services for mobile devices with no luck so far. I'm also new to moodle development so I might miss something simple so any input is appreciated.

UPDATE:

After restarting the whole docker setup and try to curl from the container again I got this message:

* Connection #0 to host webserver left intact

After further investigation I found that in config.docker-template.php there is a setting for $CFG->behat_wwwroot which has default value to http://webserver. I am not familiar how to setup testing framework in Moodle so I'm not sure how can I change this.

Now my problem is how to setup the moodle docker to both be exposed from localhost and webserver. Is anyone familiar with this?

Problem

Since you have not mentioned the port cURL tries to connect to port 80 which is the default http port. You can observe it here:

* Connected to webserver (172.18.0.8) port 80 (#0)

Solution

You need to specifically set it as 8000:

Instead of

'http://webserver/webservice/rest/server.php?wstoken=fa4e7222df472b032ca9b4bd6d17595a&moodlewsrestformat=json&wsfunction=core_user_get_users&criteria[0][key]=id&criteria[0][value]=2'

It should be

'http://webserver:8000/webservice/rest/server.php?wstoken=fa4e7222df472b032ca9b4bd6d17595a&moodlewsrestformat=json&wsfunction=core_user_get_users&criteria[0][key]=id&criteria[0][value]=2'

CodePudding user response：

you must use docker-compose to create your network.
