Docker Logs
Because most applications deployed in Replicated are running in Docker containers, a commonly used collector spec is the docker.logs collector. This will copy the output (stdout/etderr) from a docker container and include it in a support bundle.
This collector is fully documented in the reference docs.
Example
To illustrate how to use this collector, we’ll create a collector that will include the last 1000 lines from all nginx containers.
collect:
v1:
- docker.logs:
descriptino: Nginx docker container logs
output_dir: /docker/logs/nginx
timeout_seconds: 15
container_list_options:
All: true # include stopped containers
Filters:
image: "nginx"
container_log_options:
Timestamps: true
Tail: 1000 # only include 1000 linesThe above collector definition will include the logs for stdout and stderr in the /docker/logs/nginx directory for any container running from any tag of the “nginx” image.
