This project includes a playground for a demonstrator of a distributed system of storage, comprising storage elements, caches and redirectors, communicating via HTTPS.
The project consists of several docker-compose files with the purpose of either deploy the component that we are going to describe or testing them as whole local setup. The service deployed consist of :
- user interface
- storage elements
- cache (the caching server you actually contact)
- federation server
Each service must be properly configured moving to xdc_http_cache/scripts, running configure_services.sh, selecting the desired service and following the instructions provided by the script.
Please notice that configure_services.sh is developed for CentOS7 and requires to be run by a user with sudo privileges. If your OS is not CentOS7, you can run the script connect_configuration_container.sh:
this script will start a CentOS7 Docker container with this GitHub repository mounted in it; just move to /xdc_http_cache/scripts and run configure_services.sh, then exit when the configuration is completed.
The repository is splitted in folders with at least one service setup docker-compose.yml file:
- ui (user interface service)
- iam (IAM OIDC and voms-aa service)
- storage (Cache and Storm WebDAV service )
- dynafed (dynafed federator service)
Each service (apart from ui) can be started from the relevant folder with following commands:
docker-compose build
docker-compose up -d
Before doing this you have to follow the reference documentation in the Deployment and Administration section. In order to work you don't need to instantiate all the services. Depending on the needs one or more services can deployed. Recommended versions for Docker and docker-compose are (at least) the following:
Docker version 19.03.5docker-compose version 1.25.3
