 **Authentication**: Basic auth is resolved automatically by the Requests library by reading a **~/.netrc** file. Make sure
 to set up the correct entries (Sentinel and STAC host URL) there.
+
+# Docker
+1. create `.env` file - this file propagate variables to .netrc file in container
+   example:
+```
+NETRC_MACHINE1=dhr1.cesnet.cz
+NETRC_LOGIN1=
+NETRC_PASSWORD1=
+
+NETRC_MACHINE2=resto.c-scale.zcu.cz
+NETRC_LOGIN2=
+NETRC_PASSWORD2=
+```
+2. build and run with docker compose (have to run directly in directory)
+   ```
+   docker compose build
+   ```
+   ```
+   docker compose up
+   ```
+3. all files from /var/tmp/sentinel are in /mnt/data/var/tmp/sentinel
+   - it can be change in ``` docker-compose.yaml```
