在Docker中運行kong和kong dashboard

一、制作alpine版的kong鏡像

https://github.com/Kong/docker-kong/tree/d4cec3dc46c780a916a40963309554ca81da2b46/alpine
需要修改Dockerfile,增加執行權限，否則會報錯：
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為：
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到私有鏡像倉庫
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、準備，并運行kong，

可參考：https://getkong.org/install/docker/?_ga=2.142464946.1094900129.1519568988-2071034501.1509695831

先運行postgres數據庫
docker run -d –name kong-database
              -p 5432:5432
              -e “POSTGRES_USER=kong”
              -e “POSTGRES_DB=kong”
              postgres:9.4

遷移數據
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

運行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

運行kong dashboard

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