What is the method for managing Docker logs?

There are several common methods for managing Docker logs.

1. 控制台输出：默认情况下，Docker容器的日志会直接输出到控制台。可以使用docker logs命令来查看容器的日志。
2. File output: Docker container logs can be redirected to a file. You can specify the logs output to a file by using the CMD command in the Dockerfile, for example CMD [“python”, “app.py”, “>>”, “/var/log/app.log”]. You can view the logs in the file using the docker logs command.
3. Log drivers: Docker offers various pluggable log drivers that can send container logs to different destinations such as syslog, Fluentd, ELK (Elasticsearch, Logstash, Kibana), etc. You can specify the log driver by using the –log-driver parameter when creating the container, for example, docker run –log-driver=syslog.
4. Third-party tools: You can also use third-party log management tools to collect and analyze logs from Docker containers, such as ELK, Splunk, Graylog, etc. These tools offer more advanced log management and analysis features.

The appropriate log management method should be selected based on specific needs.
