搬运工，撰写JSON记录驾驶员的标签/ env的

Question

我一直在试图获取日志格式：

{"log":"Using CATALINA_BASE: /opt/apache-tomcat- 
7.0.76\r\n","stream":"stdout","time":"2017-04- 
19T04:28:33.608418994Z","attrs": 
{"production_status":"testing","os":"ubuntu"}} 

我使用泊坞窗 - compose.yml：

version: '2.1' 
services: 
    web: 
    image: hello-world/web:latest 
    container_name: api 
    ports: 
     - "80:8080" 
logging: 
    driver: "json-file" 
    options: 
    max-size: 10m 
    max-file: "3" 
    labels: testing 
    env: ubuntu 

但我不明白日志中的“attrs”键。我究竟做错了什么？

Answer 1

根据我的测试，有两件东西让标签/环境变量显示在日志中。

1. 指定哪些标签/环境变量在日志中显示
2. 将容器

因此，要得到你想要的，你需要设置docker-这些标签/环境变量compose.yml到：

version: '2.1' 
services: 
    web: 
    image: hello-world/web:latest 
    container_name: api 
    ports: 
     - "80:8080" 
    logging: 
     driver: "json-file" 
     options: 
     max-size: 10m 
     max-file: "3" 
     labels: "production_status" 
     env: "os" 
    labels: 
     production_status: "testing" 
    environment: 
     - os=ubuntu
