    As was mentioned, you cannot do any /app/data operations in the Dockerfile.

        is /tmp writeable ?
        e.g. can I prepare the app for runtime in /tmp, copy contents in start.sh and empty /tmp (for tidiness) ?

          /tmp is writeable and also created in runtime, however as the name suggests, the app should not rely on content to persist there. Traditionally it may be used as temporary storage for file uploads, of other caching files.

            @timconsidine said in Localstorage & /app/data:

            @robi I don't think I am (now).

            so what is this in Dockerfile?

            && ln -s /app/data/data /app/code/data \

            && ln -s /app/data/public /app/code/public

              @robi that's from the start.sh file which runs after Dockerfile has been built to an image.

                @timconsidine I updated my post, since it's about the ln commands not the cp commands

                  I would double check if the app was built and updated properly to use your latest Dockerfile. You can do cloudron debug and then you can cloudron exec to inspect if all the symlinks are proper. You can then launch your start.sh manually in that shell also.

                    Thank you
                    So app builds and launches, symlinks created in Dockerfile work
                    But there is weirdness in running start.sh
                    Some commands executed, some not.
                    Eg the first mkdir works but not #2 or #3
                    The first cp from tmp works but not #2 or #3
                    The chown doesn't work but the script is running to the end and working because the app launches.
                    Any ideas ?
                    Here's the start.sh :

                    #!/bin/bash
                    # set -eu
                    mkdir -p /app/data/config || true
                    mkdir -p /app/data/public || true
                    mkdir -p /app/data/images || true
                    cp -r /tmp/skeleton/* /app/data/config
                    cp -r /tmp/public/* /app/data/public 
                    cp -r /tmp/images/* /app/data/images 
                    chown -R cloudron:cloudron /app/data
                    export npm_config_cache=/app/data/.npm-cache
                    exec /usr/local/bin/gosu cloudron:cloudron npm start
                    

                    Cloudronmanifest.json has localstorage addon and proxyAuth addon.

                      @timconsidine not sure if this the main problem, but mkdir -p ... does "no error if existing, make parent directories as needed" so should run it without the || true also if essential commands don't work in start.sh the app should not just continue anways in some unknown state.

                        @nebulon thank you
                        I stuck in the || true because chatGPT told me to do so when I asked it why the script wasn't working ! 😄

                        Yep, it's weird behaviour, some lines working but some not.
                        I can execute the failed lines manually in Terminal, but not the right way to do it !

                          lol - That will just always make an exec return true / successful even when it fails.

                            Absolutely ... not !
                            I have seen some absolute shockers (hallucinations, wrong responses) but nevertheless I do find it useful.
                            Comes back to that old age truth : you can have the best sword/drill/hammer in the world, but it's only useful if you know how to use it.
                            AI is helpful ... except when it's not and you recognise it is not !

                              If you stop calling it AI, it will begin to make sense as a tool.
