Prerequisiti

Installa Docker sulla tua macchina. Puoi seguire la guida ufficiale di installazione qui.

Passaggi

1. Crea un Dockerfile

Crea un nuovo file chiamato Dockerfile nella directory del tuo progetto con il seguente contenuto:

# Base image (official Ubuntu image)
FROM ubuntu:20.04

# Set the time zone upfront to avoid interactive selection
ENV DEBIAN_FRONTEND=noninteractive
RUN ln -fs /usr/share/zoneinfo/Europe/Berlin /etc/localtime && \
    apt-get update && apt-get install -y tzdata && \
    dpkg-reconfigure --frontend noninteractive tzdata

# Install necessary packages and update package lists
RUN apt-get install -y \
    wget \
    curl \
    apt-transport-https \
    ca-certificates \
    software-properties-common \
    php-cli \
    php-cgi \
    libapache2-mod-php \
    unzip \
    openjdk-8-jdk \
    debconf \
    && rm -rf /var/lib/apt/lists/*

# Automatically accept the license agreement for installing Microsoft TrueType fonts
RUN echo "ttf-mscorefonts-installer msttcorefonts/accepted-mscorefonts-eula select true" | debconf-set-selections

# Install Microsoft TrueType fonts
RUN apt-get update && \
    apt-get install -y ttf-mscorefonts-installer && \
    rm -rf /var/lib/apt/lists/*

# Install Tomcat - using version 9.0.93
RUN wget https://archive.apache.org/dist/tomcat/tomcat-9/v9.0.93/bin/apache-tomcat-9.0.93.tar.gz -O /tmp/tomcat.tar.gz && \
    tar xzf /tmp/tomcat.tar.gz -C /opt/ && \
    mv /opt/apache-tomcat-9.0.93 /opt/tomcat && \

    unzip /tmp/php-java-bridge.zip -d /tmp/php-java-bridge && \
    mkdir -p /opt/tomcat/webapps/JavaBridge && \
    cp /tmp/php-java-bridge/JavaBridge.war /opt/tomcat/webapps/JavaBridge && \
    cd /opt/tomcat/webapps/JavaBridge && \
    jar -xvf JavaBridge.war && \
    rm -rf /tmp/php-java-bridge.zip /tmp/php-java-bridge

# Download and install Aspose.Slides for PHP via Java
RUN wget https://github.com/aspose-slides/Aspose.Slides-for-PHP-via-Java/archive/refs/heads/master.zip -O /tmp/aspose-slides.zip && \
    unzip /tmp/aspose-slides.zip -d /tmp/aspose-slides && \
    mkdir -p /opt/tomcat/webapps/JavaBridge/WEB-INF/lib && \
    mkdir -p /tmp/sample && \
    cp /tmp/aspose-slides/Aspose.Slides-for-PHP-via-Java-master/jar/*.jar /opt/tomcat/webapps/JavaBridge/WEB-INF/lib && \
    cp -r /tmp/aspose-slides/Aspose.Slides-for-PHP-via-Java-master/lib /tmp/sample && \
    rm -rf /tmp/aspose-slides.zip /tmp/aspose-slides

# Create the test.php file
RUN echo '<?php\n\

# Create the entrypoint.sh script
RUN echo '#!/bin/bash\n\

# Explicitly grant execute permissions to the script
RUN chmod 755 /tmp/entrypoint.sh

# Expose port 8080 for Tomcat and port 9000 for PHP/Java Bridge
EXPOSE 8080
EXPOSE 9000

# Set the working directory
WORKDIR /tmp

# Start Tomcat when the container starts
ENTRYPOINT ["/tmp/entrypoint.sh"]

2. Costruisci l’immagine Docker

Esegui il seguente comando nella directory dove si trova il tuo Dockerfile per costruire l’immagine Docker:

docker build -t aspose-slides-php-java .

3. Avvia il container Docker

Una volta costruita l’immagine, avvia il container:

docker run -p 8080:8080 aspose-slides-php-java

4. Accesso a Aspose.Slides in Docker

Dopo aver avviato il container, lo script genererà un file PDF. Puoi trovare il file di output generato output.pdf nella cartella /tmp all’interno del container:

docker exec -it <container-id> ls /tmp

Per copiare il file PDF generato sulla tua macchina locale, esegui il seguente comando:

docker cp <container-id>:/tmp/output.pdf ./output.pdf
