如何在 gitlab-runner 中发布端口？

Question

I want to deploy a container on my server with gitlab-runner (docker executor) and then get response from my local browser.

I have the most simple dockerfile that start an nginx:

FROM nginx:alpine
COPY /nginx.conf /etc/nginx/conf.d/default.conf
EXPOSE 80

And my nginx config looks like this:

server {
    listen 80;
    location / {
        root /usr/share/nginx/html;
        index index.html index.htm;
        try_files $uri $uri/ /index.html =404;
    }

}

Here's my.gitlab.yml:

image: docker:latest
services: 
  - docker:dind

variables:
  WORK_DIR: ${CI_PROJECT_NAME}
  BRANCH: ${CI_COMMIT_REF_NAME}
  REGISTRY: registry.gitlab.com/myusername/cicdtest

stages:
  - build
  - deploy

build_project:
    stage: build
    script:
        - docker login -u $CI_REGISTRY_USER -p $CI_REGISTRY_PASSWORD $CI_REGISTRY
        - docker build -t $REGISTRY .
        - docker push $REGISTRY



deploy_project:
    stage: deploy
    script:
        - docker login -u $CI_REGISTRY_USER -p $CI_REGISTRY_PASSWORD $CI_REGISTRY
        - docker pull $REGISTRY
        - docker stop $(docker ps -a -q) || true && docker rm $(docker ps -a -q) || true
        - docker run --name=$BRANCH -p 80:80 -itd $REGISTRY   

And my config.toml:

[[runners]]
  name = "name1"
  url = "https://gitlab.com/"
  token = "secret"
  executor = "docker"
  [runners.custom_build_dir]
  [runners.cache]
    [runners.cache.s3]
    [runners.cache.gcs]
  [runners.docker]
    tls_verify = false
    image = "docker:alpine"
    privileged = true
    disable_entrypoint_overwrite = false
    oom_kill_disable = false
    disable_cache = false
    volumes = ["/cache", "/var/run/docker.sock:/var/run/docker.sock"]
    shm_size = 0

By the way everything with docker and nginx works fine in localhost.

Now when I push to repo all the pipelines get the passed status and every line is executed fine but when I try to access my container from my local browser with url 185.xxx.xx.xx I can't get any responses. It's like gitlab-runner didn't publish any ports.

Can't help your with a solution right now but Im here to help. At first please inspect the running docker container and see if your idea, that the ports are not set up correctly, is right:

[docker inspect [OPTIONS] NAME|ID [NAME|ID...]]
