    Hi All, I am trying to install docker-ce on linux vm
    I am getting following error

    --> Finished Dependency Resolution
    Error: Package: containerd.io-1.4.9-3.1.el7.x86_64 (docker-ce-stable)

     You could try using --skip-broken to work around the problem
     You could try running: rpm -Va --nofiles --nodigest

    my linux version is as follows

    $ uname -a
    Linux testvm 3.10.0-1127.13.1.el7.x86_64 #1 SMP Fri Jun 12 14:34:17 EDT 2020 x86_64 x86_64 x86_64 GNU/Linux

    Please guide me how can I install docker on my linux vm?

    Stop using it in windows. It has been designed fir Linux, and that's where it runs best.

    Linux has more drivers available than windows. Try it with a live version, you'll see.

    hello guys,
    hope you are all well.
    I faced output clipped, log limit 1MiB reached error while building a container.
    I added to /etc/docker/daemon.json these 2 lines:

      "log-driver": "json-file",
      "log-opts": {"max-size": "10m", "max-file": "3"}

    I ran systemctl reload docker. The error displayed 3 times when rebuilding.
    any advice about how to handle properly this issue ?
    PS: I don't want to use buildx since I am in production.

    Hello.

    How can I delete images that were created the LAST X hours? The "until" filter is not what I'm looking for.
    Thanks!

    Hi All
    iam getting below error while trying to login ecr from ansible playbokk
    FAILED! => {"changed": false, "msg": "Error connecting: Error while fetching server API version: ('Connection aborted.', error(104, 'Connection reset by peer'))"}

    Hi all,
    I have an 'interesting' problem:
    Setup is this:
    • two docker-servers, both with their own IP-address
    • VRRP (virtual router) providing floating 'Virtual IP' address
    • on both servers, a container running 'tftpd' (tftp-daemon)
    Problem is the TFTP process:
    -> incomming UDP/69 packet from client to server to initiate the TFTP
    -> additional UDP session is set up (on a different source and destination port) from the server to the client
    in our setup:
    • client sends UDP/69 to Virtual IP-address, which arrives at on the docker containers
    • server sets up UDP session to the client, .. using the PHYSICAL IP-address of the docker server
    kristoff - on1arf
    @krbonne:gnuradio.org
    [m]
    so the client says 'I'm setting up a TFTP to one ip-address, and get a reverse TFTP session from a different IP-address' and ignores it
    so ... question. .. if a docker-host has two ip-addresses on an ethernet interface, can you tell it to use the secundairy IP-address for the outgoing NAT-sessions by (one or all) containers, and not the primary?

    hey guys, I created the dockerfile which I want to push it as an image to the gitlab registry
    but at the time of docker login, I get a warning like this:

    WARNING! Your password will be stored unencrypted in ~/.docker/config.json.
    Configure a credential helper to remove this warning. See
    https://docs.docker.com/engine/reference/commandline/login/#credentials-store
    
    Login Succeeded

    what should I do?
    some people have written this as a solution:

    Your only workaround would be to install docker-credential-pass in your home directory so that Docker will use that instead of docker-credential-secretservice. docker-credential-pass does not require a GUI.

    please advise, what I should do now
