基于nginx的码头图像为什么拒绝VSCode中的连接

Question

考虑以下设置：

devcontainer.json

{
  "name": "Deputy devcontainer",
  "dockerComposeFile": "docker-compose.yml",
  "service": "go-development",
  "settings": {
    "go.toolsManagement.checkForUpdates": "local",
    "go.useLanguageServer": true,
    "go.gopath": "/go"
  },
  "extensions": [
    "golang.Go",
    "gitlab.gitlab-workflow",
    "GitHub.copilot",
    "eamodio.gitlens",
    "zxh404.vscode-proto3",
    "bungcip.better-toml"
  ],
  "workspaceFolder": "/workspace",
  "remoteUser": "vscode"
}

docker-compose.yml

version: '3'

services:
  go-development:
    image: my-custom-docker-repository/go-development:latest
    command: /bin/sh -c "while sleep 1000; do :; done"
    volumes:
      - ..:/workspace:cached
      - ./deputy-cli-configuration.toml:/home/vscode/.deputy/configuration.toml
    user: vscode

  deputy-package-server:
    image: my-custom-docker-repository/deputy-package-server:latest
    ports:
      - "8080:8080"
    volumes:
      - ./deputy-packages:/var/opt/deputy/deputy-package-server/package
      - ./deputy-repository:/var/opt/deputy/deputy-package-server/repository
    environment:
      - RUST_LOG=debug

  index-repository:
    image: my-custom-docker-repository/deputy-repository-server
    volumes:
      - ./deputy-repository/.git:/srv/git/index.git
    ports:
      - "8082:80"

Dockerfile for index-repository

FROM teamfruit/nginx-fcgiwrap

RUN apt-get update && apt-get upgrade -y
RUN apt-get install git-core fcgiwrap -y
COPY nginx.conf /etc/nginx/conf.d/default.conf

nginx.conf in index-repository

server {
    listen       80;

    location ~ /git(/.*) {
        client_max_body_size            0;

        fastcgi_param SCRIPT_FILENAME     /usr/lib/git-core/git-http-backend;
        include       fastcgi_params;

        fastcgi_param   GIT_HTTP_EXPORT_ALL   "";
        fastcgi_param   GIT_PROJECT_ROOT    /srv/git;
        fastcgi_param   PATH_INFO           $1;
        fastcgi_pass   unix:/var/run/fcgiwrap.socket;
    }
}

Dockerfile for go-development

FROM vscode/devcontainers/go

RUN apt-get update && apt-get upgrade -y
RUN apt-get install protobuf-compiler make debhelper dpkg-dev -y
RUN go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@v1.2
RUN go install google.golang.org/protobuf/cmd/protoc-gen-go@v1.28
RUN chmod 777 -R /go/pkg

当运行vscode-devcontainer时，git clone http://index-repository/git/index.git是不可能的，这在connection refused中失败。

​

​

但是，当我试图直接在index-repository或主机中克隆时，这些命令就会成功。此外，连接到deputy-package-server (一个简单的锈菌网络服务器)工作，没有任何问题。

​

​

我还可以从tcpdump中看到请求实际上到达了nginx-container

​

​

我还使用dig来验证dns不是问题。

​

​

到目前为止，我真的很困惑为什么这种联系总是被拒绝。我怀疑这个问题可能存在于nginx配置的某个地方，但无法说明在哪里。我做错了什么？

Answer 1

您正在映射端口"8082:80"，因此您应该通过http://index-repository:8082的http://localhost:8082 isntead访问index-repository容器。

如果您想通过域名index-repository访问存储库服务器容器，您应该公开存储库服务器容器的端口80 (主机名将与服务id一样默认在码头网络中，例如。index-repository)。

然后，dev容器可以以http://index-repository:80的形式访问它。
