Services launch#

This section gives examples for launching LIM containers.

The sequence of launching LIM services is as follows:

To launch LIM services, the LP 5 must be deployed.

It is recommended to launch containers one by one and wait for the container status to become "up" (use the docker ps command).

When launching each service, certain parameters are used, for example, --detach, --network, etc. See the section "Launching parameters description" for more detailed information about all launch parameters of LUNA PLATFORM services and databases.

See the "Docker commands" section for details about working with containers.

Python Matcher proxy container launch#

Use the following command to launch the service:

docker run \
--env=CONFIGURATOR_HOST=127.0.0.1 \
--env=CONFIGURATOR_PORT=5070 \
--env=PORT=5110 \
--env=WORKER_COUNT=1 \
--env=RELOAD_CONFIG=1 \
--env=RELOAD_CONFIG_INTERVAL=10 \
--env=SERVICE_TYPE="proxy" \
-v /etc/localtime:/etc/localtime:ro \
-v /tmp/logs/python-matcher-proxy:/srv/logs \
--name=luna-python-matcher-proxy \
--restart=always \
--detach=true \
--network=host \
dockerhub.visionlabs.ru/luna/luna-python-matcher:v.1.9.6

Indexer container launch#

Use the following command to launch the service:

docker run \
--env=CONFIGURATOR_HOST=127.0.0.1 \
--env=CONFIGURATOR_PORT=5070 \
--env=PORT=5180 \
--env=WORKER_COUNT=1 \
--env=RELOAD_CONFIG=1 \
--env=RELOAD_CONFIG_INTERVAL=10 \
-v /etc/localtime:/etc/localtime:ro \
-v /tmp/logs/lim-indexer:/srv/logs \
-v /var/lib/luna/lim_storage:/srv/local_storage \
--name=lim-indexer \
--restart=always \
--detach=true \
--network=host \
dockerhub.visionlabs.ru/luna/lim-indexer:v.0.5.1

The deployment of the Indexer service should be done on a separate server, because building an index takes a lot of resources for a long time. One Indexer instance can only build one index at a time, so it is recommended to run multiple indexer instances. The indexer must be also configured with storage, which must be large enough.

Index Manager container launch#

Use the following command to launch the service:

docker run \
--env=CONFIGURATOR_HOST=127.0.0.1 \
--env=CONFIGURATOR_PORT=5070 \
--env=PORT=5190 \
--env=WORKER_COUNT=1 \
--env=RELOAD_CONFIG=1 \
--env=RELOAD_CONFIG_INTERVAL=10 \
-v /etc/localtime:/etc/localtime:ro \
-v /tmp/logs/lim-manager:/srv/logs \
-v /var/lib/luna/lim_storage:/srv/local_storage \
--name=lim-manager \
--restart=always \
--detach=true \
--network=host \
dockerhub.visionlabs.ru/luna/lim-manager:v.0.5.1

It is recommended to run at least two manager instances for redundancy purposes. Since task management is carried out through the Redis, if one manager is down, the second one will be able to continue its work from the instant step.

Indexed Matcher container launch#

Use the following command to launch the service:

docker run \
--env=CONFIGURATOR_HOST=127.0.0.1 \
--env=CONFIGURATOR_PORT=5070 \
--env=PORT=5200 \
--env=WORKER_COUNT=1 \
--env=RELOAD_CONFIG=1 \
--env=RELOAD_CONFIG_INTERVAL=10 \
-v /etc/localtime:/etc/localtime:ro \
-v /tmp/logs/lim-matcher:/srv/logs \
-v /var/lib/luna/lim_storage:/srv/local_storage \
--name=lim-matcher \
--restart=always \
--detach=true \
--network=host \
dockerhub.visionlabs.ru/luna/lim-matcher:v.0.5.1

Indexed Matcher does not communicate with other LIM services. It only monitors the storage, and when indices appear it loads them into memory. Since matching requests processing is carried out through the Redis streams, any number of matcher instances could be run without any system config updates. The number of Indexed Matcher instances should be determined by performance requirements.

For each instance of the Indexed Matcher service, you can set an environment variable VL_LIM_MATCHER_HOST indicating its IP address. This can be useful for separating monitoring data into different instances. For example, you can determine how many instances are in work, which instance caused the error, which indexes are in operation, etc.
