Installing Aspose.Slides for PHP via Java Using Docker

Prerequisites:

• Install Docker on your machine. You can follow the official installation guide here.

Steps:

1. Create Dockerfile

Create a new file named Dockerfile in your project directory with the following content:

# 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 && \
    rm /tmp/tomcat.tar.gz

# Install PHP/Java Bridge
RUN curl -L http://sourceforge.net/projects/php-java-bridge/files/Binary%20package/php-java-bridge_7.2.1/php-java-bridge_7.2.1_documentation.zip/download -o /tmp/php-java-bridge.zip && \
    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\
require_once("http://localhost:8080/JavaBridge/java/Java.inc");\n\

# Create the entrypoint.sh script
RUN echo '#!/bin/bash\n\
# Start Tomcat in the background\n\
catalina.sh start\n\
# Wait for Tomcat to fully start\n\
until curl -s http://localhost:8080 > /dev/null; do\n\

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

# Configure php.ini
RUN echo "allow_url_include = On" >> /etc/php/7.4/cli/php.ini

# Set environment variables for Tomcat
ENV CATALINA_HOME /opt/tomcat
ENV PATH $CATALINA_HOME/bin:$PATH
ENV PHP_CLASSPATH /opt/aspose-slides/lib

# 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. Build Docker Image

Run the following command in the directory where your Dockerfile is located to build the Docker image:

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

3. Run Docker Container

Once the image is built, run the container:

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

4. Access Aspose.Slides in Docker

After starting the container, the script will generate a PDF file. You can find the generated output file output.pdf in the /tmp folder inside the container:

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

To copy the generated PDF file to your local machine, run the following command:

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