# Docker Log Input Plugin
|
|
|
|
The docker log plugin uses the Docker Engine API to get logs on running
|
|
docker containers.
|
|
|
|
The docker plugin uses the [Official Docker Client][] to gather logs from the
|
|
[Engine API][].
|
|
|
|
**Note:** This plugin works only for containers with the `local` or
|
|
`json-file` or `journald` logging driver.
|
|
|
|
[Official Docker Client]: https://github.com/moby/moby/tree/master/client
|
|
[Engine API]: https://docs.docker.com/engine/api/v1.24/
|
|
|
|
### Configuration
|
|
|
|
```toml
|
|
[[inputs.docker_log]]
|
|
## Docker Endpoint
|
|
## To use TCP, set endpoint = "tcp://[ip]:[port]"
|
|
## To use environment variables (ie, docker-machine), set endpoint = "ENV"
|
|
# endpoint = "unix:///var/run/docker.sock"
|
|
|
|
## When true, container logs are read from the beginning; otherwise
|
|
## reading begins at the end of the log.
|
|
# from_beginning = false
|
|
|
|
## Timeout for Docker API calls.
|
|
# timeout = "5s"
|
|
|
|
## Containers to include and exclude. Globs accepted.
|
|
## Note that an empty array for both will include all containers
|
|
# container_name_include = []
|
|
# container_name_exclude = []
|
|
|
|
## Container states to include and exclude. Globs accepted.
|
|
## When empty only containers in the "running" state will be captured.
|
|
# container_state_include = []
|
|
# container_state_exclude = []
|
|
|
|
## docker labels to include and exclude as tags. Globs accepted.
|
|
## Note that an empty array for both will include all labels as tags
|
|
# docker_label_include = []
|
|
# docker_label_exclude = []
|
|
|
|
## Optional TLS Config
|
|
# tls_ca = "/etc/telegraf/ca.pem"
|
|
# tls_cert = "/etc/telegraf/cert.pem"
|
|
# tls_key = "/etc/telegraf/key.pem"
|
|
## Use TLS but skip chain & host verification
|
|
# insecure_skip_verify = false
|
|
```
|
|
|
|
#### Environment Configuration
|
|
|
|
When using the `"ENV"` endpoint, the connection is configured using the
|
|
[CLI Docker environment variables][env]
|
|
|
|
[env]: https://godoc.org/github.com/moby/moby/client#NewEnvClient
|
|
|
|
