issue1: redis

• custom log's folder, and mounted to specify folder in the host machine:

  • this can look-up MySQL dockerFile: permission issue
  • or change config file: logfile "redis.log", then redis.log will appear in /data/

• copy parent folder to contianer: localtion issue

  • The path must be inside the context of the build; you cannot ADD ../something/something, because the first step of a docker build is to send the context directory (and subdirectories) to the docker daemon.
  • solution2: can also use docker-compose to specify dockerfile location

issue2: elasticsearch

1. description

   • OK: define ENV, which can be used in runtime for startup app

   • ERROR: when I define runner.sh to startup app, and then I do create file in this shell, will get follow error log

     touch: cannot touch '/usr/share/elasticsearch/plugins/analysis-ik/config/custom.dic': Permission denied
     

2. 这里想法是不对的, 在 compose.yml 文件中动态指定 ik 的目录是没有意义的

   • 在 build image 时配置文件已经修改了, 所以无效
   • 除非在 *.sh 内写动态修改配置文件的逻辑

3. solution

   • consider the usage of privileged
