-Update, run, inspect and stop server:
+# Vorraussetzungen
-```
+
-docker-compose pull
+Folgendes wird in Linux gemacht (es ist aber nicht zwingend ein eigenes Linux erforderlich):
-docker-compose up -d
+
-docker-compose logs -f --tail=10
+* Erstellen und bearbeiten von Dateien (Shell oder GUI)
-docker-compose down
+* Starten von Programmen auf der Commandline
-```
+
-Login to nextcloud
+## Installation in Ubuntu Linux
-```
+
-docker-compose exec --user www-data app bash
+``` bash
+sudo apt install docker-compose
+sudo adduser <user> docker # allow docker as user
+su <user> # relogin or reboot system to apply new group
 ```
 
-Login to mysql
+## Ohne Linux
-```
-docker-compose exec db bash
-apt update
-apt install vim less mysqltuner
 
+### Verwenden einer virtuellen Maschine mit Linux
+
+Z.B. mit _Virtual Box_ kann ein virtueller Rechner aufgesetzt werden.
+
+### Verbinden über ssh auf einen Linux-Rechner
+
+Wer kein eigenes Linux hat, kann sich über ssh mit einem Linux-Rechner verbinden, z.B. mit _Putty_. In diesem Fall ist es gut, wenn man auch Dateien auf der Commandline editieren kann.
+
+### Verwenden von Windows Subsystem for Linux
+
+Das geht wohl auch irgendwie, aber nicht besonders gut.
+
+# Hello-World Projekt erstellen
+
+## Mit git
+
+``` bash
+git clone https://git.hilie.de/toptica/docker-compose-workshop.git hello-world
+cd hello-world
+git checkout hello-world
+```
+
+## Ohne git
+
+``` bash
+mkdir hello-world
+cd hello-world
+vi docker-compose.yaml # Datei »docker-compose.yaml« erstellen und bearbeiten
+```
+
+Inhalt für docker-compose.yaml:
+``` yaml
+version: '3'
+
+services:
+  hello_world:
+    image: hello-world:latest
+```
+
+# Hello-World Projekt ausführen
+``` bash
+docker-compose up
+```
+
+Folgende Ausgabe sollte unter anderem so ähnlich erscheinen:
+``` bash
+Recreating dockercompose_hello_world_1 ... 
+Recreating dockercompose_hello_world_1 ... done
+Attaching to dockercompose_hello_world_1
+hello_world_1  | 
+hello_world_1  | Hello from Docker!
+hello_world_1  | This message shows that your installation appears to be working correctly.
+hello_world_1  | 
+hello_world_1  | To generate this message, Docker took the following steps:
+hello_world_1  |  1. The Docker client contacted the Docker daemon.
+hello_world_1  |  2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
+hello_world_1  |     (amd64)
+hello_world_1  |  3. The Docker daemon created a new container from that image which runs the
+hello_world_1  |     executable that produces the output you are currently reading.
+hello_world_1  |  4. The Docker daemon streamed that output to the Docker client, which sent it
+hello_world_1  |     to your terminal.
+hello_world_1  | 
+hello_world_1  | To try something more ambitious, you can run an Ubuntu container with:
+hello_world_1  |  $ docker run -it ubuntu bash
+hello_world_1  | 
+hello_world_1  | Share images, automate workflows, and more with a free Docker ID:
+hello_world_1  |  https://hub.docker.com/
+hello_world_1  | 
+hello_world_1  | For more examples and ideas, visit:
+hello_world_1  |  https://docs.docker.com/get-started/
