public void pushDataToOPA() throws IOException, InterruptedException {
    ProcessBuilder pb = new ProcessBuilder("curl", "-X", "PUT", "-H", "\"Content-Type: application/json\"", "-d",
            "@data.json", dataUrl);
    Process p = pb.start();
    p.waitFor();

}

When I deploy my spring boot application to a Linux server, this data.json file is not put to the target (dataUrl) when this pushDataToOPA method is called. But when I run my application in locally, it successfully puts the JSON file to the same target (dataUrl).

 public void updatePolicy() throws IOException, InterruptedException {
    ProcessBuilder pb = new ProcessBuilder("curl", "-X", "PUT", "--data-binary", "@policy.rego", policyUrl);
    Process p = pb.start();
    p.waitFor();
}

but this method is working on both sides.

CodePudding user response：

You can redirect the process output to a file with the following code:

public void updatePolicy() throws IOException, InterruptedException {
        ProcessBuilder pb = new ProcessBuilder();
        pb.command("curl", "-X", "PUT", "--data-binary", "@policy.rego", policyUrl);
        pb.redirectOutput(new File("outputfilePath"));
        pb.redirectError(new File("errorFilePath"));
        Process p = pb.start();
        p.waitFor();
        }

public void pushDataToOPA() throws IOException, InterruptedException {
        ProcessBuilder pb = new ProcessBuilder("curl", "-X", "PUT", "-H", "\"Content-Type: application/json\"", "-d",
                "@data.json", dataUrl);
        pb.redirectOutput(new File("outputfilePath"));
        pb.redirectError(new File("errorFilePath"));
        Process p = pb.start();
        p.waitFor();
    }
