導入Base image
從已有項目拷貝 nginx base image
docker save -o nginx.tar.gz nginx:xxxx
docker load -i nginx.tar.gz
docker push nginx:xxxx
docker tag nginx:xxxx nls-nginx:19.5
測試鏡像是否正常工作:
#使用內置的 start-nginx.py 部署nginx
docker run --name nginx-nls -d -p 8080:80 nls-nginx:19.5
#手動啓動 nginx要設置 ‘daemon off’
docker run --name nginx-nls -d -p 8080:80 localhost:5000/nls- nginx:vNLS.5G.19.5.3 nginx -g ‘daemon off;’ -c /etc/nginx/conf/nginx.conf
編寫部署文件
