如何在dockerfile中设置gbak

Question

我有一个 API 需要 gbak 才能工作，因为此调用：

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();

我创建了一个像这样的dockerfile：

# 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"]

但是当我尝试运行图像时，我遇到了这个错误：

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

        at java.base/java.lang.ProcessBuilder.start(ProcessBuilder.java:1109)
        ... 4 more

我尝试将我的 dockerfile 更改为：

# 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"]

但是我无法创建图像，这是错误：

 => 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

我该如何解决我的问题？

我尝试更改 dockerfile，以具有 gbak 依赖项，但出现另一个错误。

Alpine 软件包存储库中似乎没有 firebird 软件包？ 我建议尝试在 dockerfile 中手动下载并安装 firebird 数据库服务器工具，类似于此：

# 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

考虑到我伪造了 github 链接，您需要根据您的要求更改它。让我知道手动安装是否可以解决您的问题
