how to set gbak in dockerfile

I have an API that needs gbak to work cause of this call:

String command = "gbak -b -v -g -user " + username + " -password " + password + " " + databasePath + " " + backupPathUpdated;

ProcessBuilder processBuilder = new ProcessBuilder(command.split(" "));
processBuilder.redirectErrorStream(true);
Process process = processBuilder.start();

process.waitFor();

I created a dockerfile like this:

# Use an official OpenJDK runtime as a parent image
FROM openjdk:17-alpine

# Set the working directory to /app
WORKDIR /app

# Copy the current directory contents into the container at /app
COPY . /app

# Make port 8080 available to the world outside this container
EXPOSE 8080

# Run application when the container launches
CMD ["java", "-jar", "target/poc-docker-0.0.1-SNAPSHOT.jar"]

When I tried to run the image, I faced this error:

Java.io.IOException: Cannot run program "gbak": error=2, No such file or directory
    at java.base/java.lang.ProcessBuilder.start(ProcessBuilder.java:1142)

    ... 4 more

I tried to change my dockerfile to this:

# Use an official OpenJDK runtime as a parent image
FROM openjdk:17-alpine

# Set the working directory to /app
WORKDIR /app

# Install gbak
RUN apk --no-cache add firebird

# Copy the current directory contents into the container at /app
COPY . /app

# Make port 8080 available to the world outside this container
EXPOSE 8080

# Run application when the container launches
CMD ["java", "-jar", "target/poc-docker-0.0.1-SNAPSHOT.jar"]

but then I can't create a image, this is the error:

 => ERROR [3/4] RUN apk --no-cache add firebird                                                                                                          1.3s 
   8 | >>> RUN apk --no-cache add firebird
   9 |
  10 |     # Copy the current directory contents into the container at /app
--------------------

How can I solve my problem?

I tried to change dockerfile, to have gbak dependency, but I had another error.

UPDATE:

I could solve using this in my dockerfile:

RUN apk --no-cache add wget tar procps xz make build-base
&& wget https://github.com/FirebirdSQL/firebird/releases/download/v4.0.4/Firebird-4.0.4.3010-0.i686.tar.gz
&& tar -xzf Firebird-4.0.4.3010-0.i686.tar.gz
&& cd Firebird-4.0.4.3010-0.i686
&& ls -l
&& wget https://github.com/libtom/libtommath/releases/download/v1.2.0/ltm-1.2.0.tar.xz
&& tar -xJf ltm-1.2.0.tar.xz
&& cd libtommath-1.2.0
&& make
&& make install
&& cd ../
&& apk del wget tar xz make build-base
&& rm -rf /var/cache/apk/* /app

Solution

  • It seems that the package firebird is not available in the Alpine package repositories. I would suggest trying to manually download and install the Firebird database server tools in your dockerfile, something similar to this:

    # firebird download and install
RUN wget https://github.com/FirebirdSQL/firebird/releases/download/R3_0_9/Firebird-3.0.9.53074-0.amd64.tar.gz \
    && tar -xzf Firebird-3.0.9.53074-0.amd64.tar.gz \
    && cd Firebird-3.0.9.53074-0.amd64 \
    && ./install.sh -silent

    Consider that I fabricated the GitHub link, you will need to change it based on your requirements. Let me know if manually installing it solves your issues.
