# Vortrags-Script: Docker Basics
|
||||
|
||||
## Einführung
|
||||
|
||||
### Container vs. VM
|
||||
- **Virtuelle Maschinen**: Eigenes Betriebssystem, Hypervisor, hoher Ressourcenverbrauch
|
||||
- **Container**: Teilen Kernel des Host-Systems, leichtgewichtige Isolation, schneller Start
|
||||
|
||||
### Docker-Architektur
|
||||
- **Docker-Client**: CLI-Tool für Interaktion
|
||||
```bash
|
||||
docker version
|
||||
docker info
|
||||
```
|
||||
- **Docker-Daemon**: Hintergrundprozess, verwaltet Container und Images
|
||||
- **Docker-Registry**: Repository für Images
|
||||
```bash
|
||||
docker search nginx
|
||||
```
|
||||
|
||||
### Images und Container
|
||||
- **Image**: Unveränderbare Vorlage
|
||||
```bash
|
||||
docker images
|
||||
```
|
||||
- **Container**: Laufende Instanz eines Images
|
||||
```bash
|
||||
docker ps
|
||||
```
|
||||
|
||||
## Schaubild File-Layerstruktur in Containern
|
||||
|
||||

|
||||
|
||||
## Docker-Images
|
||||
|
||||
### Image-Aufbau
|
||||
- Layer-Architektur: Jede Anweisung erzeugt neue Schicht
|
||||
```bash
|
||||
docker history nginx
|
||||
```
|
||||
- Cache-Nutzung bei Build-Prozessen
|
||||
- Basis-Images als Fundament
|
||||
```bash
|
||||
docker pull php:8.1-fpm
|
||||
```
|
||||
|
||||
### Dockerfile-Syntax
|
||||
```dockerfile
|
||||
FROM php:8.1-fpm
|
||||
WORKDIR /var/www/html
|
||||
COPY composer.json composer.lock ./
|
||||
RUN apt-get update && apt-get install -y \
|
||||
zip \
|
||||
unzip \
|
||||
&& docker-php-ext-install pdo pdo_mysql
|
||||
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
|
||||
RUN composer install --no-scripts --no-autoloader
|
||||
COPY . .
|
||||
RUN composer dump-autoload --optimize
|
||||
EXPOSE 9000
|
||||
CMD ["php-fpm"]
|
||||
```
|
||||
|
||||
### Build-Prozess
|
||||
```bash
|
||||
docker build -t mein-projekt:1.0 .
|
||||
docker build -t mein-projekt:1.0 -f Dockerfile.prod .
|
||||
docker build --no-cache -t mein-projekt:1.0 .
|
||||
```
|
||||
|
||||
### Image-Registry
|
||||
```bash
|
||||
docker login
|
||||
docker tag mein-projekt:1.0 username/mein-projekt:1.0
|
||||
docker push username/mein-projekt:1.0
|
||||
docker pull username/mein-projekt:1.0
|
||||
```
|
||||
|
||||
## Container-Lebenszyklus
|
||||
|
||||
### Starten, Stoppen, Löschen
|
||||
```bash
|
||||
docker run -d --name web mein-projekt:1.0
|
||||
docker run -it --rm ubuntu bash
|
||||
docker stop web
|
||||
docker start web
|
||||
docker restart web
|
||||
docker rm web
|
||||
docker rm -f web
|
||||
docker ps
|
||||
docker ps -a
|
||||
```
|
||||
|
||||
### Container-Isolation
|
||||
```bash
|
||||
docker inspect web
|
||||
docker stats web
|
||||
```
|
||||
|
||||
### Ports und Netzwerke
|
||||
```bash
|
||||
docker run -d -p 8080:80 nginx
|
||||
docker network ls
|
||||
docker network create app-netz
|
||||
docker run -d --network app-netz --name db mysql:8.0
|
||||
docker network inspect app-netz
|
||||
```
|
||||
|
||||
### Volumes für Datenpersistenz
|
||||
```bash
|
||||
docker volume ls
|
||||
docker volume create data-volume
|
||||
docker run -v $(pwd):/var/www/html nginx
|
||||
docker run -v data-volume:/var/lib/mysql mysql:8.0
|
||||
docker run --tmpfs /tmp nginx
|
||||
docker volume inspect data-volume
|
||||
```

# Vortrags-Script: Docker Compose Basics
|
||||
|
||||
## Einführung Docker Compose
|
||||
|
||||
### Zweck und Vorteile
|
||||
- **Definition**: Tool zur Verwaltung mehrerer Container als Anwendung
|
||||
- **Installation prüfen**:
|
||||
```bash
|
||||
docker-compose --version
|
||||
```
|
||||
|
||||
### YAML-Syntax
|
||||
```yaml
|
||||
version: '3'
|
||||
services:
|
||||
web:
|
||||
image: nginx
|
||||
ports:
|
||||
- "8080:80"
|
||||
db:
|
||||
image: mysql:8.0
|
||||
environment:
|
||||
MYSQL_ROOT_PASSWORD: secret
|
||||
```
|
||||
|
||||
### Grundbefehle
|
||||
```bash
|
||||
docker-compose up
|
||||
docker-compose up -d
|
||||
docker-compose down
|
||||
docker-compose ps
|
||||
docker-compose logs
|
||||
docker-compose logs -f web
|
||||
```
|
||||
|
||||
## Mehrcontainer-Anwendungen
|
||||
|
||||
### Service-Abhängigkeiten
|
||||
```yaml
|
||||
services:
|
||||
web:
|
||||
depends_on:
|
||||
- db
|
||||
```
|
||||
|
||||
```bash
|
||||
docker-compose up -d db
|
||||
docker-compose up -d web
|
||||
```
|
||||
|
||||
### Umgebungsvariablen
|
||||
```bash
|
||||
echo "DB_PASSWORD=secret" > .env
|
||||
docker-compose up -d
|
||||
```
|
||||
|
||||
### Netzwerke zwischen Containern
|
||||
```bash
|
||||
docker-compose exec web ping db
|
||||
docker network ls
|
||||
docker network inspect <project_name>_default
|
||||
```
|
||||
|
||||
## Docker Compose in Entwicklung
|
||||
|
||||
### Hot-Reloading
|
||||
```bash
|
||||
docker-compose exec web ls -la /var/www/html
|
||||
# Änderung an lokaler Datei vornehmen
|
||||
docker-compose exec web cat /var/www/html/index.php
|
||||
```
|
||||
|
||||
### Debugging
|
||||
```bash
|
||||
docker-compose logs -f
|
||||
docker-compose exec web bash
|
||||
docker-compose exec -T web php -v
|
||||
```
|
||||
|
||||
### Ressourcenkontrolle
|
||||
```bash
|
||||
docker stats $(docker-compose ps -q)
|
||||
```
|
||||
|
||||
## Zusammenfassung und Beispiel
|
||||
|
||||
### Komplettes Beispiel: LAMP-Stack
|
||||
```yaml
|
||||
version: '3'
|
||||
services:
|
||||
web:
|
||||
build: ./php
|
||||
ports:
|
||||
- "8000:80"
|
||||
volumes:
|
||||
- ./src:/var/www/html
|
||||
depends_on:
|
||||
- db
|
||||
environment:
|
||||
DB_HOST: db
|
||||
DB_USER: app
|
||||
DB_PASSWORD: secret
|
||||
DB_NAME: myapp
|
||||
|
||||
db:
|
||||
image: mysql:8.0
|
||||
volumes:
|
||||
- db-data:/var/lib/mysql
|
||||
environment:
|
||||
MYSQL_ROOT_PASSWORD: rootsecret
|
||||
MYSQL_DATABASE: myapp
|
||||
MYSQL_USER: app
|
||||
MYSQL_PASSWORD: secret
|
||||
|
||||
phpmyadmin:
|
||||
image: phpmyadmin/phpmyadmin
|
||||
ports:
|
||||
- "8080:80"
|
||||
environment:
|
||||
PMA_HOST: db
|
||||
depends_on:
|
||||
- db
|
||||
|
||||
volumes:
|
||||
db-data:
|
||||
```
|
||||
|
||||
### Praktische Befehle
|
||||
```bash
|
||||
# Alle Container starten
|
||||
docker-compose up -d
|
||||
|
||||
# Status prüfen
|
||||
docker-compose ps
|
||||
|
||||
# Service neu erstellen und starten
|
||||
docker-compose up -d --force-recreate web
|
||||
|
||||
# Logs überwachen
|
||||
docker-compose logs -f
|
||||
|
||||
# Alles herunterfahren und aufräumen
|
||||
docker-compose down -v --remove-orphans
|
||||
|
||||
# Neu bauen und starten
|
||||
docker-compose build --no-cache
