Hybrid installation

This installation method is almost identical to the manual installation, so please refer to that chapter first. The only difference is that some of the dependent services, namely PostgreSQL, Redis and optionally Elasticsearch, are run via Docker containers and do not need to be installed separately.

Installing the dependencies

The only additional dependency that is needed for this type of installation is Docker. For this step, please refer to the installation via Docker. The installation of Docker Compose can be skipped, as it will not be needed.

Running the services

PostgreSQL can be run via the following command, which will expose port 5432 of the container and persist all data in a named volume called postgres:

sudo docker run --name postgres -d -p 5432:5432 -v postgres:/var/lib/postgresql/data -e POSTGRES_DB=kadi -e POSTGRES_USER=kadi -e POSTGRES_PASSWORD=kadi postgres:13

Redis can be run via the following command, which will expose port 6379 of the container and persist all data in a named volume called redis:

sudo docker run --name redis -d -p 6379:6379 -v redis:/data redis:5

Elasticsearch can be run via the following command, which will expose port 9200 of the container and persist all data in a named volume called elasticsearch:

sudo docker run --name elasticsearch -d -p 9200:9200 -v elasticsearch:/usr/share/elasticsearch/data -e discovery.type=single-node -e xpack.security.enabled=false -e "ES_JAVA_OPTS=-Xms512m -Xmx512m" elasticsearch:7.15.1

For more information about managing the containers, please refer to the official documentation of Docker.
