cd aprocontainer 

./launchsas.sh

sudo docker logs -f sas-analytics-pro

docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' sas-analytics-pro

6 - Get inside SAS Analytics Pro on Viya container and set permissions on keys/folders

sudo docker exec -it sas-analytics-pro bash

su sasdemo

chmod -R 700 /data

cd data/.ssh

chmod 600 authorized_keys id_rsa id_rsa.pub
