# Docker部署
Micro易于在docker容器中運行
## 預置的鏡像
[Docker Hub](https://hub.docker.com/r/microhq/)上提供了預置的鏡像
## 安裝Micro
```
docker pull microhq/micro
```
## Compose
使用docker compose運行本地部署
```
consul:
command: -server -bootstrap -rejoin
image: progrium/consul:latest
hostname: "registry"
ports:
- "8300:8300"
- "8400:8400"
- "8500:8500"
- "8600:53/udp"

## 從頭開始構建
Dockerfile包含在倉庫中。
```
FROM alpine:3.2
RUN apk add --update ca-certificates && \
rm -rf /var/cache/apk/* /tmp/*
ADD micro /micro
WORKDIR /
ENTRYPOINT [ "/micro" ]
```
### 構建二進制
```
CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -ldflags '-w' -i -o micro ./main.go
```
### 構建鏡像
```
docker build -t micro .
```
