在Docker中运行kong和kong dashboard

一、制作alpine版的kong镜像

https://github.com/Kong/docker-kong/tree/d4cec3dc46c780a916a40963309554ca81da2b46/alpine
需要修改Dockerfile,增加执行权限，否则会报错：
Error response from daemon: invalid header field value “oci runtime error: container_linux.go:247: starting container process caused “exec: /”/docker-entrypoint.sh/”: permission denied”n”.

修改后Dockerfile为：
FROM alpine:3.6
LABEL maintainer Marco Palladino, marco@mashape.com

ENV KONG_VERSION 0.12.1
ENV KONG_SHA256 9f699e20e7d3aa6906b14d6b52cae9996995d595d646f9b10ce09c61d91a4257

RUN apk add –no-cache –virtual .build-deps wget tar ca-certificates
&& apk add –no-cache libgcc openssl pcre perl tzdata
&& wget -O kong.tar.gz “https://bintray.com/kong/kong-community-edition-alpine-tar/download_file?file_path=kong-community-edition-$KONG_VERSION.apk.tar.gz”
&& echo “$KONG_SHA256 *kong.tar.gz” | sha256sum -c –
&& tar -xzf kong.tar.gz -C /tmp
&& rm -f kong.tar.gz
&& cp -R /tmp/usr /
&& rm -rf /tmp/usr
&& cp -R /tmp/etc /
&& rm -rf /tmp/etc
&& apk del .build-deps

COPY docker-entrypoint.sh /docker-entrypoint.sh
RUN chmod +x /docker-entrypoint.sh
ENTRYPOINT [“/docker-entrypoint.sh”]

EXPOSE 8000 8443 8001 8444

STOPSIGNAL SIGTERM

CMD [“/usr/local/openresty/nginx/sbin/nginx”, “-c”, “/usr/local/kong/nginx.conf”, “-p”, “/usr/local/kong/”]
~

二、Tag后push到私有镜像仓库
docker tag kong:0.12.1-alpine xx.xx.xx.xx:5000/kong:0.12.1-alpine
docker push xx.xx.xx.xx:5000/kong:0.12.1-alpine

三、准备，并运行kong，

可参考：https://getkong.org/install/docker/?_ga=2.142464946.1094900129.1519568988-2071034501.1509695831

先运行postgres数据库
docker run -d –name kong-database
-p 5432:5432
-e “POSTGRES_USER=kong”
-e “POSTGRES_DB=kong”
postgres:9.4

迁移数据
docker run –rm
–link kong-database:kong-database
-e “KONG_DATABASE=postgres”
-e “KONG_PG_HOST=kong-database”
-e “KONG_CASSANDRA_CONTACT_POINTS=kong-database”
kong:0.12.1-alpine kong migrations up

运行Kong
docker run -d –name kong
–link kong-database:kong-database
-e “KONG_PG_HOST=kong-database”
-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”
-e “KONG_ADMIN_LISTEN_SSL=0.0.0.0:8444”
-p 8000:8000
-p 8443:8443
-p 8001:8001
-p 8444:8444
Kong:0.12.1-alpine

运行kong dashboard

参考：https://github.com/PGBI/kong-dashboard
docker run –name kong-dashboard -d -p 8084:8080 pgbi/kong-dashboard:v2
