目标
由于公司容器化上生产后，需要规范发布流程，而作为容器的基础服务harbor镜像仓库，通过自己来发布自己不太理，于是将镜像方式的harbor组件变更为进程方式发布。由于已经上线较长时间，各系统的配置诸如环境变量、配置文件、日志告警相关的一堆流程已配置过。改代码编译问题好办，如何让原来的环境变量、配置文件、日志文件等均不变化是目前需要解决的问题
环境
centos 7.2
1、harbor jobserivce ui为一套代码共用base config服务对于两服务的配置项CONFIG_PATH指向的配置文件不同，主要涉及分离端口监听问题
CONFIG_PATH=/apps/conf/harbor/jobservice/app.conf
CONFIG_PATH=/apps/conf/harbor/ui/app.conf
/apps/conf/harbor/jobservice/app.conf
httpport = 8080
/apps/conf/harbor/ui/app.conf
httpport = 8088
解决
环境变量问题可以通过systemd的EnvironmentFile变量解决

环境变量文件
cat
/apps/conf/harbor/jobservice/env
HARBOR_DB_HOST=
'192.168.1.23'
HARBOR_DB_PORT=3306
HARBOR_DB_USER=
'root'
HARBOR_DB_PASSWORD=
'1xxxv'
CONFIG_PATH=
/apps/conf/harbor/jobservice/app
.conf
systemd配置文件引用环境变量文件
cat
/usr/lib/systemd/system/harbor-jobservice
.service
[Service]
EnvironmentFile=
/apps/conf/harbor/jobservice/env
ExecStart=
/apps/svr/harbor/jobservice
启动该服务时相当于为该进程执行过一次
export
，不影响其他系统服务
export
VIP_HARBOR_DB_HOST=
'192.168.1.23'
export
VIP_HARBOR_DB_PORT=3306
export
VIP_HARBOR_DB_USER=
'root'
export
VIP_HARBOR_DB_PASSWORD=
'1xxxv'
export
CONFIG_PATH=
/apps/conf/harbor/jobservice/app
.conf

2、日志问题，进程由systemd接管后，日志写入到/var/log/messages里，现要将jobservice registry ui三个组件的日志分开写，每个日志的监控级别不同，registry日志里的error关键字并一定是错误，不分开写会错误日志报警问题
解决
该问题可以结合systemd与rsyslog服务配置共同处理具体处理如下
