include docker secrets?

[fherreazcue]

there might be enough time left over to include them and the .env file (see #148 )

[OliverWoolland]

my idea is:

• create a secret (spuc_pass) add to spucsvi
• spucsvi then does an http basic auth prompt, password can be entered to view spucsvi
• we point out that this auth is limited to this one service, only one user - how can we do better? microsevices
