将配置置于一个secret中，并mount到pod的环境变量中

kubectl create secret generic -n tt doc-server \
	--from-literal=GITLAB_TOKEN=123456798123456798 \
	--from-literal=GITHUB_TOKEN=123456798123456798 \
	--from-literal=GIT_ORIGIN="https://oauth:token@gitlab.example.com/king/doc-server.git" \
	--from-literal=LOCAL_DIR=/tmp/data \
	--from-literal=REDIS_URL= \
	--from-literal=CORP_ID= \
	--from-literal=CORP_AGENT_SECRET= \
	--from-literal=CORP_AGENT_ID=

关于多副本的问题

在多副本的情况下，考虑到github/gitlab回调，通过nginx反向代理，或者kubernete的service，一般只有一台收到请求，这会导致不同的副本的数据不一致

解决这个问题的办法是，通过一个临时的目录[volumes/emptyDir]来共享多副本的数据
