Install Libreoffice (JodConverter) with dockerfile

Hi,

I use alfresco-content-repository-community:7.3.1 (docker)

I need to use jodconverter in java process. So I updated my Dockerfile as follow, in order to install LibreOffice :

#Installing LibreOffice
COPY backend/LibreOffice_6.3.5.2_Linux_x86-64_rpm /usr/local/LibreOffice_6.3.5.2_Linux_x86-64_rpm
RUN cd /usr/local/LibreOffice_6.3.5.2_Linux_x86-64_rpm/RPMS/
RUN yum -y install /usr/local/LibreOffice_6.3.5.2_Linux_x86-64_rpm/RPMS/*.rpm;

I find libreoffice6.3 in /opt folder inside container. However "libreoffice -_version" says :

bash: libreoffice: command not found

When the java process is executed i get the following error: ServiceManager' started but its pid could not be found :

This is my java code :

libreOfficeHome = libreoff.getValue();
        
        File initialFile = new File(workPath + "/" + fileName);
        LocalOfficeManager localOfficeManager = LocalOfficeManager.builder()
                .install()
                .officeHome(libreOfficeHome) //your path to openoffice
                .build();

        try {
            localOfficeManager.start();
            final DocumentFormat format = DocumentFormat.builder()
                    .from(DefaultDocumentFormatRegistry.DOCX)
                    .build();

            LocalConverter
                  .make()
                  .convert(new FileInputStream(initialFile))
                  .as(DefaultDocumentFormatRegistry.getFormatByMediaType("application/msword"))
                  .to(new File(targetFile))
                  .as(format)
                  .execute();

        } catch (Exception e) {
            logger.error("ERROR convertToDocx: " + ExceptionUtils.getStackTrace(e));
            return null;
        } finally {
            OfficeUtils.stopQuietly(localOfficeManager);
        }

Same error with libreoffice 7.5

How can I solve that ? Thx

I think -version is not an option available. Try --help

Probably docker container is not able to execute the command to find the process id. Once your container is up try to manually access 'ps' command and see if it is still working. Also try to see if you can manually kill any process using "kill" command.

You may have to install procps : https://yum-info.contradodigital.com/view-package/installed/procps/

look for appropriate command to install based on the your linux version. ACS 7.3 is based on rockylinux.
