kong网关之DB-less部署

一：起kong容器

docker network create kong-net        #新建子网
docker run -d --name kong \
     --network=kong-net \
     -v "kong-vol:/usr/local/kong/declarative" \
     -e "KONG_DATABASE=off" \
     -e "KONG_PROXY_ACCESS_LOG=/dev/stdout" \
     -e "KONG_ADMIN_ACCESS_LOG=/dev/stdout" \
     -e "KONG_PROXY_ERROR_LOG=/dev/stderr" \
     -e "KONG_ADMIN_ERROR_LOG=/dev/stderr" \
     -e "KONG_ADMIN_LISTEN=0.0.0.0:8001, 0.0.0.0:8444 ssl" \
     -p 8000:8000 \
     -p 8443:8443 \
     -p 8001:8001 \
     -p 8444:8444 \
     kong:latest

二：生成kong.conf和kong.yml并修改

docker exec -it kong kong config init /home/kong/kong.yml    #初始化出kong.yml
##替换kong.yml内容如下
_format_version: '1.1'

docker exec -it -u root 93a4f8c026c4 /bin/bash    #以root用户进入，否则无权限
cp -rp /etc/kong/kong.conf.default /etc/kong/kong.conf
将kong.conf文件database改为database = off ，将declarative_config改为declarative_config = /home/kong/kong.yml

###commit成新的镜像并save保存
docker commit 93a4f8c026c4 kong:202108251623
docker save cf6b7eca8102 >/root/kong-202108251623.tar
