This will work against input like following:

AWS_ACCESS_KEY_ID: dGVzdAo=
AWS_SECRET_ACCESS_KEY: c2VjcmV0Cg==
DB_URL: cG9zdGdyZXNxbDovL3VzZXI6c2VjcmV0QGRiLW5hbWUuc29tZXRoaW5nLnVzLXdlc3QtMi5yZHMuYW1hem9uYXdzLmNvbTo1NDMyL2RiCg==

And actually this example above will work without the extra echo.
cat secrets.yml |awk -F: '{ printf "export %s=",$1; system ("echo "$2"|base64 -d ")}'

But when getting output from kubernetes secrets you will need that extra echo to give newline. At least that is one way to do it.
