Additional information#

This section provides the following additional information:

Steps to perform descriptors matching#

To start the descriptors matching procedure using LIM services, you should perform the following steps:

  • select the preferred mode that will be used for the descriptors matching - one-time or automatic.
  • One-time mode: Specify the required "list_id" in the request body to the "create task" resource of the Index Manager service and perform the request.
  • Automatic mode for working with specific lists: Specify the required "list_id" in the "indexing_lists" setting of the "LIM_MANAGER_INDEXING" of the Configurator service.
  • Automatic mode for working with all existing lists:
    • Specify the "dynamic" value in the "indexing_lists" setting of the "LIM_MANAGER_INDEXING" of the Configurator service.
    • Specify the minimum number of faces in the list in the "min_indexing_list_size" setting of the "LIM_MANAGER_INDEXING" of the Configurator service to index all existing descriptors in the lists.
  • Send a request for matching descriptors from the API service.

For details on LIM service interaction, see the "Service interaction" section of the LIM administrator manual.

Docker commands#

Show containers#

To show the list of launched Docker containers use the command:

docker ps

To show all the existing Docker containers use the command:

docker ps -a

Copy files to container#

You can transfer files into the container. Use the docker cp command to copy a file into the container.

docker cp <file_location> <container_name>:<folder_inside_container>

Enter container#

You can enter individual containers using the following command:

docker exec -it <container_name> bash

To exit the container, use the command:

exit

Images names#

You can see all the names of the images using the command:

docker images

Delete image#

If you need to delete an image:

  • Run the docker images command.
  • Find the required image, for example dockerhub.visionlabs.ru/luna/luna-image-store.
  • Copy the corresponding image ID from the IMAGE ID, for example, "61860d036d8c".
  • Specify it in the deletion command:
docker rmi -f 61860d036d8c

Delete all the existing images.

docker rmi -f $(docker images -q)

Stop container#

You can stop the container using the command:

docker stop <container_name>

Stop all the containers:

docker stop $(docker ps -a -q)

Delete container#

If you need to delete a container:

  • Run the "docker ps" command.
  • Stop the container (see Stop container).
  • Find the required image, for example dockerhub.visionlabs.ru/luna/luna-image-store.
  • Copy the corresponding container ID from the CONTAINER ID column, for example, "23f555be8f3a".
  • Specify it in the deletion command:
docker container rm -f 23f555be8f3a

Delete all the containers.

docker container rm -f $(docker container ls -aq)

Check service logs#

You can use the following command to show logs for the service:

docker logs <container_name>

Logging to server#

To enable saving logs to the server, you should:

  • Create directories for logs on the server.
  • Activate log recording and set the location of log storage inside LP service containers.
  • Configure synchronization of log directories in the container with logs on the server using the volume argument at the start of each container.

Docker Compose script is already configured to synchronize directories with the folders created in the section below.

Create logs directory#

You need to create the following directories for storing logs and assign them the appropriate rights.

mkdir -p /tmp/logs/lim-manager /tmp/logs/lim-indexer /tmp/logs/lim-matcher /tmp/logs/python-matcher-proxy

chown -R 1001:0 /tmp/logs/lim-manager /tmp/logs/lim-indexer /tmp/logs/lim-matcher /tmp/logs/python-matcher-proxy

Logging activation#

To enable logging to file, you need to set the log_to_file and folder_with_logs settings in the <SERVICE_NAME>_LOGGER section of the settings for each service.

Automatic method

To update logging settings, you can use the logging.json settings file provided with the distribution package.

Run the following command after starting the Configurator service:

docker cp /var/lib/luna/lim-current/example-docker/configs/logging.json luna-configurator:/srv/luna_configurator/used_dumps/logging.json

Update your logging settings with the copied file.

docker exec -it luna-configurator python3 ./base_scripts/db_create.py --dump-file /srv/luna_configurator/used_dumps/logging.json

Manual method

Go to the Configurator service interface (127.0.0.1:5070) and set the logs path in the container in the folder_with_logs parameter for all services whose logs need to be saved. For example, you can use the path /srv/logs.

Set the log_to_file option to true to enable logging to file.
