Purpose
The previous article introduced how to install k8s on two Tencent Clouds. This article will create a docker image on the k8s master (Tencent Cloud xxxx), and run the hecheng_be service in docker to facilitate subsequent deployment of this docker to k8s
Environment construction
1. Install git
yum install -y git
复制代码2. Pull the code from github to the specified directory
cd /home/workspaces/go/src/hecheng_be
git clone https://github.com/XXX/hecheng_be.git
复制代码Write Dockfile
FROM golang:1.17.5
WORKDIR /app
# 使用阿里源替换 debian 源
RUN sed -i 's/deb.debian.org/mirrors.aliyun.com/g' /etc/apt/sources.list
RUN apt-get update && \
apt-get install unzip && \
apt-get install libprotobuf-dev -y
ENV HOME=/root
COPY go.mod go.sum ./
ENV GO111MODULE=on
ENV GOPROXY=https://goproxy.cn
RUN git config --global url.https://[email protected]/treelab/.insteadOf https://github.com/treelab/
RUN go install github.com/cosmtrek/air@latest
RUN go install github.com/go-delve/delve/cmd/dlv@latest
RUN go install github.com/golang/mock/[email protected]
RUN go install github.com/vektra/mockery/v2/.../
ENV PATH="${PATH}:${HOME}/.local/bin"
RUN go mod download
COPY . .
EXPOSE 50051 8080 2345
CMD ["air", "-c", ".air.toml"]
复制代码3. Make a docker image
docker build -f Dockerfile -t docker_repo_usename/hecheng_be_docker_image .
复制代码Note that the name here must be docker_repo_usename/iamge_name, otherwise it cannot be pushed to the remote end. View after production is complete
docker image ls
复制代码4. Push the created mirror to the far end
Log in
docker login
复制代码push to the far end
docker push docker_repo_usename/hecheng_be_docker_image
复制代码The next article will introduce running this image in k8s
