ctafrontend docker image repository

• This is the repository for CERN Tape Archive frontend docker image.

Aim

The aim of this project is to provide a CTA frontend through Docker® containers.

Components

• Dockerfile - The file describing how to build the Docker image for building CASTOR, in turn.
• etc/yum.repos.d - directory containing yum repos for installing necessary packages.
• etc/xrootd - directory containing static configuration files for xrootd
• run.sh - The main script to setup runtime environment.

Setup

In order to be able to use the container, you should have Docker installed on your machine. You can get more information on how to setup Docker here.

The base image used is CERN CentOS 7 (gitlab-registry.cern.ch/linuxsupport/cc7-base).

Build image

In order to build the image, after making sure that the Docker daemon is running, run from the repository directory:

docker build --force-rm -t ctafrontend-cc7 cc7/

After the image has finished building successfully, run the following command:

# Run CTA fronted with prepared object store and catalogue DB. 
# All logs will be passed back to the docker host through /dev/log socket. 
# Shared path must be passed inside to the container.
# A host name have to be used for the container  to run xrootd.
#
# @param objectstore  CTA object store directory path name.
# @param catdb        CTA catalogue DB setup.
#

docker run -h ctasystestf.cern.ch -it -e objectstore="/shared/jobStoreVFS1FlpYW" -e catdb="sqlite:/shared/sqliteDb/db" -v /dev/log:/dev/log -v /opt/cta/docker:/shared ctafrontend-cc7
