ska-tango-images-tango-dsconfig

This image contains json2tango provided by dsconfig. json2tango allows loading Tango configuration from a json file into a Tango database.

Summary

Release 0.6.3 of ska-tango-images provides the 1.8.3 tag of the ska-tango-images-tango-dsconfig OCI image.

The image uses ska-tango-images-tango-python as a base image and so provides the same features, in addition to the json2tango utility.

Warning

For compatibility reasons, the working directory for this image is “/” as opposed to “/home/tango”. As the default user is still “tango”, this image does not have the permissions required to write to the working directory.

Usage Example

To produce a JSON dump of the contents of a Tango database running at TANGO_HOST to the file tango-dump.json:

docker run --rm --env TANGO_HOST=$TANGO_HOST --net=host \
   artefact.skao.int/ska-tango-images-tango-dsconfig:1.8.3 \
   python -m dsconfig.dump > tango-dump.json

To load the same JSON dump (found in the current directory) back into the Tango database:

docker run --rm --env TANGO_HOST=$TANGO_HOST --net=host -v .:/mnt:z \
   artefact.skao.int/ska-tango-images-tango-dsconfig:1.8.3 \
   json2tango --write /mnt/tango-dump.json
