參考github上的dockerfile https://github.com/Kong/docker-kong/tree/master/centos ，在dockefile裏面添加自定義的內容進行進行編譯。本例中在官方的例子上安裝了telnet、iproutes等軟件包，同時爲了實現網關的後續的應用程序認證鑑權，增長了graphql的lua擴展模塊git

準備dockerfile

wget https://codeload.github.com/Kong/docker-kong/zip/refs/tags/2.3.2
unzip docker-kong-2.3.2.zip
cd docker-kong-2.3.2/centos/

FROM centos:7
LABEL maintainer="Kong <support@konghq.com>"

ARG ASSET=ce
ENV ASSET $ASSET

ARG EE_PORTS

COPY kong.rpm /tmp/kong.rpm

ARG KONG_VERSION=2.3.2
ENV KONG_VERSION $KONG_VERSION

ARG KONG_SHA256="aad05b5b7425a0c1dc3095363c785a4147d3cd91064f0221a2a818c7bdcc97dc"

RUN set -ex; \
  if [ "$ASSET" = "ce" ] ; then \
    curl -fL "https://bintray.com/kong/kong-rpm/download_file?file_path=centos/7/kong-$KONG_VERSION.el7.amd64.rpm" -o /tmp/kong.rpm \
    && echo "$KONG_SHA256 /tmp/kong.rpm" | sha256sum -c -; \
  fi; \
  yum install -y -q unzip shadow-utils git net-tools iproute langpacks-zh_CN telnet lrzsz \
  && yum clean all -q \
  && rm -fr /var/cache/yum/* /tmp/yum_save*.yumtx /root/.pki \
  # Please update the centos install docs if the below line is changed so that
  # end users can properly install Kong along with its required dependencies
  # and that our CI does not diverge from our docs.
  && yum install -y /tmp/kong.rpm \
  && yum clean all \
  && rm /tmp/kong.rpm \
  && chown kong:0 /usr/local/bin/kong \
  && chown -R kong:0 /usr/local/kong \
  && luarocks install graphql && \  
  if [ "$ASSET" = "ce" ] ; then \
    kong version ; \
  fi;

COPY docker-entrypoint.sh /docker-entrypoint.sh

USER kong

ENTRYPOINT ["/docker-entrypoint.sh"]

EXPOSE 8000 8443 8001 8444 $EE_PORTS

STOPSIGNAL SIGQUIT

CMD ["kong", "docker-start"]

編譯推送docker鏡像

docker build -t harbor.59iedu.com/fjhb/kong:2.3.2 .
docker push harbor.59iedu.com/fjhb/kong:2.3.2

更新運行中的docker

修改k8s的deployment文件，替換鏡像版本後進行apply
涉及到版本升級，須要進入init-container wait-for-migrations，分別執行下列命令，不然proxy和ingress-controller沒法成功啓動
```
kong migrations up
kong migrations finish
```
