How to view Docker logs
Docker logs are an invaluable resource for diagnosing and solving container problems. Here are three ways to view Docker logs:
1. Use docker logs command
The docker logs command is the easiest way to view logs. It outputs the standard output and error stream of the specified container.
<code>docker logs CONTAINER_NAME</code>
For example, to view the logs of a container named "my-container", you can use the following command:
<code>docker logs my-container</code>
2. Use docker exec command
The docker exec command allows you to run commands in a container. You can use this command to view log files.
<code>docker exec -it CONTAINER_NAME /bin/sh</code>
You can then view the log file using the following command:
<code>cat /var/log/CONTAINER_NAME.log</code>
For example, to view the log file of a container named "my-container", you can use the following command:
<code>docker exec -it my-container /bin/sh cat /var/log/my-container.log</code>
3. Use Docker Compose
If you use Docker Compose to manage your application, you can use the <code>docker-compose logs</code> command to view the logs. This command will output logs for all services.
<code>docker-compose logs</code>
For example, to view the logs of a Docker Compose application named "my-app", you can use the following command:
<code>docker-compose -f docker-compose.yml logs</code>
