add_docker_metadata processor annotates each event with relevant metadata
from Docker containers:
- Container ID
When running Journalbeat in a container, you need to provide access to
Docker’s unix socket in order for the
add_docker_metadata processor to work.
You can do this by mounting the socket inside the container. For example:
docker run -v /var/run/docker.sock:/var/run/docker.sock ...
To avoid privilege issues, you may also need to add
--user=root to the
docker run flags. Because the user must be part of the docker group in order
/var/run/docker.sock, root access is required if Journalbeat is
running as non-root inside the container.

It has the following settings:
(Optional) Docker socket (UNIX or TCP socket). It uses
- (Optional) SSL configuration to use when connecting to the Docker socket.
- (Optional) A list of fields to match a container ID, at least one of them should hold a container ID to get the event enriched.
(Optional) A list of fields that contain process IDs. If the
process is running in Docker then the event will be enriched. The default value
(Optional) Match container ID from a log path present in the
sourcefield. Enabled by default.
(Optional) Match container short ID from a log path present
sourcefield. Disabled by default. This allows to match directories names that have the first 12 characters of the container ID. For example,
(Optional) Index in the source path split by
/to look for container ID. It defaults to 4 to match
- (Optional) Time of inactivity to consider we can clean and forget metadata for a container, 60s by default.
(Optional) Default to be false. If set to true, replace dots in
