    I am guessing the addresses in his image are "small". How is that a problem? Those memory locations are virtual addresses so it is just normal.

    docker-compose with -d
    deleted my persistent volume
    is it normal ?
    every time when I run a docker with -d , it deletes my volume (or atleast I can't see mysql created db) when I spin up mysql container

    @onriv what do you mean? and how is that related to the image you posted?

    I'm sorry, it's unrelated to docker. I compiled a c++ program and included a wrong version of header files of a dependency. (at that time I though it maybe a docker related problem)

    can anyone forward me to any channel specific to docker content trust. Notary server!
    I am doing a POC and facing issues
    src/github.com/go-sql-driver/mysql/driver.go undefined: driver.connector
    go version
    go1.15 linux/amd64
    any help is appreciated
    my manager is killing me 🤪🤪🤪
    I found that it was possible with go version higher than 1.10 and looking at the v 1.15 it should be supported right?

    How can i i write files to disk from a springboot app docker image? Whats the best strategy to address this requirement?
    the app has to upload and save images on disk and also display them on angular app and also the files should be downoloadedable from angular app

    Does anyone have this problem? after I updated to the latest version of Docker, I can't now connect to any of my containers' databases, like mongo always throws that auth failed. I searched but not found any solution that worked. Everything was working fine in the previous version

    Phase > <@gitter_niuziyuanpy:matrix.org> [graphdriver] prior storage driver overlay2 failed: driver not supported

    If I remember correctly, I got this after an upgrade of docker. Luckily, thx to the upgrade, they were no container needed on the machine. Thus, I moved the content of /var/lib/docker to somewhere else. A reboot of the docker daemon later, the daemon started correctly. Be careful, it had lost all its images.

    @matrixbot I don't understand

    Haley The filesystem format is not the same (the way the files/layers are saved under /var/lib/docker.).
    Haley Only way to cope with that, is:
    Haley 1. Before the upgrade of the OS/Docker version, save all layers/images you need as tar files using the save command.
    Haley 2. upgrade the OS, but remove docker
    Haley 3. delete /var/lib/docker
    Haley 4. install docker again (new version). make sure it runs.
    Haley 5. Import the saved images

    Haley had that when moving from old debian to debian 9 .. What a pain it was :}
    matrixbot
    @matrixbot
    Phase It's either an update of the OS or of docker.
    喵喵喵
    @NiuziyuanPy
    docker update
    matrixbot
    @matrixbot
    Phase Is it working now? What helped?
    matrixbot
    @matrixbot
    Haley It is docker update. With the new debian version came a new docker version which changed the default filesystem overlay format.

    I had the same issue also it's just the person ask for help and then disappear... Not a big fan of this behavior.

    Phase What means QAQ?
    Phase I never had this issue to create the DOCKER chain...
    Phase Can you do it by hand? With root user? The command line it gives looks valid. I would try a:
    sudo iptables -t nat -N DOCKER

        build:
          context: .
          dockerfile: Dockerfile.dev
        command: npm install && npm run start:dev
        environment:
