Docker

通常微服务情景时，或按服务交付时，我们使用docker部署。

dockerfile
  2. # =============== build and run ===============
  3. # build:  docker build -t go-service:latest .
  4. # run:    docker run -dit go-service:latest
  7. # =============== build stage ===============
  8. FROM golang:1.16.5-buster AS build
  9. # env
  10. ENV GOOS=linux \
  11.     GOARCH=amd64 \
  12.     CGO_ENABLED=0 \
  13.     GO111MODULE=on \
  14.     GOPROXY="https://goproxy.cn,direct"
  15. # dependent
  16. WORKDIR /app
  17. COPY go.* ./
  18. RUN go mod download -x all
  19. # build
  20. COPY . ./
  21. # ldflags:
  22. #  -s: disable symbol table
  23. #  -w: disable DWARF generation
  24. # run "go tool link -help" to get the full list of ldflags
  25. RUN go env && go build -ldflags "-s -w" -o go-service -v ./main.go
  29. # =============== final stage ===============
  30. FROM alpine:latest AS final
  31. # resources
  32. WORKDIR /app
  33. COPY --from=build /app/go-service ./
  34. COPY --from=build /app/conf/base.toml ./conf/base.toml
  35. COPY --from=build /app/conf/prod ./conf/prod
  36. # set time zone
  37. RUN apk add --no-cache tzdata
  38. # expose
  39. EXPOSE 80
  40. ENTRYPOINT ["env","GO_ENV=prod","/app/go-service", "-other", "flags"]

nginx

当我们主机部署时，单机多域名服务时，就加一层nginx做转发。

http

  1. server {
  2.   listen 80;
  3.     server_name test.com;
  4.     root /rootdir;
  6.     location ~ /services{
  7.         #go 服务器可以指定到其他的机器上，这里设定本机服务器的6666端口
  8.         proxy_pass  http://127.0.0.1:6666;
  9.         #Proxy Settings
  10.         proxy_redirect     off;
  11.         proxy_set_header   Host             $host;
  12.         proxy_set_header   X-Real-IP        $remote_addr;
  13.         proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
  14.         #proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
  15.         #proxy_max_temp_file_size 0;
  16.         #proxy_connect_timeout      90;
  17.         #proxy_send_timeout         90;
  18.         #proxy_read_timeout         90;
  19.         #proxy_buffer_size          4k;
  20.         #proxy_buffers              4 32k;
  21.         #proxy_busy_buffers_size    64k;
  22.         #proxy_temp_file_write_size 64k;
  23.     }
  24. }

websocket

  1. {
  2.     http{
  3.          map $http_upgrade $connection_upgrade {
  4.              default upgrade;
  5.              ''      close;
  6.         }
  7.     }
  9.       // other...
  10.     server {
  11.       listen 80;
  12.         server_name test.com;
  13.         root /rootdir;
  15.         location ~ /services{
  16.             proxy_pass http://127.0.0.1:8888;
  17.             #Proxy Settings
  18.             proxy_redirect     off;
  19.             proxy_set_header   Host             $host;
  20.             proxy_set_header   X-Real-IP        $remote_addr;
  21.             proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
  22.                   # websocket
  23.             proxy_http_version 1.1;
  24.             proxy_set_header Upgrade $http_upgrade;
  25.             proxy_set_header Connection $connection_upgrade;
  26.             proxy_read_timeout         300s; #keeplive
  27.         }
  28.     }
  30. }
