Docker. Logging.

Docker

Experiment with Docker continue! Now I need to configure logs using Fluentd. I have a next technical task:

  1. Create /data/logs directory on host system with 777 permitions.
  2. Run container with name fluentd with next parameters:
    • The container must be available on port 24224
    • /fluentd/log directory inside the container must be mounted to the /data/logs on host system
    • Image is fluentd:latest
  3. Run container with name nginx with next parameters:
    • Image is nginx:latest
    • Logging driver is fluentd
    • Fluentd server’s address is `127.0.0.1:24224’

As a result, we have following commands:

mkdir /data/logs  # create directory
chmod 777 /data/logs/  # set permitions
docker run -d --name fluentd -v /data/logs/:/fluentd/log \ 
           -p 24224:24224 fluentd:latest # run fluentd
docker run -d --name nginx --log-driver=fluentd \
           --log-opt fluentd-address=127.0.0.1:24224 \
           -p 8080:80 nginx:latest # run nginx
