Docker container images installation help

    Soma


    Thank you for time and understanding,

    I have followed videos and read and have some understanding what is required but obviously not enough as i have used root. I will follow you guide and hopefully i will succeed.

    So when I create a folder ~/tmp/config with the conf file in it and run docker run -it -p 1883:1883 -p 9001:9001 -v ~/tmp/config:/mosquitto/config -v /mosquitto/data -v /mosquitto/log eclipse-mosquitto all is working.

    Thanks to you both, comments are not hash, the only thing i can say as newbie is we t and you get over whelmed . This when some help from guys like you comes in. Now i know that i need a user name in the docker group i can hopefully go on from here.


    thanks again.

    Well, too many ways to "kill a mosquitto", :D (pun intended) ;)

    The reason to have a dedicated user for docker is for safety. It's not really "demanding".

    But, with an "unpriviledge" user, even if there's a "hole", that user won't be able to have much access to the system.


    Just take your time and go step by step.


    I'll also try to make this into a ".yml" file to be more easy to deploy on Portainer or with "docker-compose"


    If you have any hiccups, just post it and we'll go from there.

    I don't have a dedicated user for docker, but my user that I added to the docker group and runs my docker stuff does not have sudo or any other elevated privileges. It's just my main user..


    I agree w/ you though on the need for an unprivileged user to be running containers.

    Yep, I also have my "regular" user added to the docker group (not a exclusive one) but with the same principle: no sudo or other elevated priviledges. :)

    Hi

    I have followed the install steps to create a user in docker group. this i found already exist, so i added my user name. Then logged out of Terminal to log back in for step to to go to /home/user. this is were the confusion sets in.

    I ssh into OMV thru PI or Mike @192.168 ( relevant password) i would normally cd to the relevant file , however this has proved to be incorrect.


    I am struggling on how to get to the docker cd /home/ user to complete the process. Again after looking thru countless pages on the web & docker i am afraid i am getting nowhere. I know that username is registered in sudo.docker group see below.


    I appreciate that i will be frustrating for you to after nurse me thru this but once it in its in? ( well this procedure anyway).

    Please be aware that a user with control over the docker daemon (aka in the docker group) effectively has elevated privileges due to the capabilities of the docker daemon.

    log back in for step to to go to /home/user. this is were the confusion sets in

    When you login with a user, you're already at "/home/<username>"

    You can see it with this as soon as you login: pwd


    That's where I was guiding you to do the folders (dir).

    sorry but i have an error Unable to open Mosquitto config / mosquitto.conf



    Code

See 'docker run --help'.

    I checked the nano mosquitto./config/mosquitto.conf it is fine, as you can see i tried again to load it?

    I check the nano conf it was

    Zitat von MIkey6283

    -it --name mosquitto -p 1883:1883 -v/home/mike/docker-mosqui

    You missed a SPACE between -v AND /home.... ;)


    Can you show the output of: cat /home/mike/docker-mosquitto/mosquitto/config/mosquitto.conf???


    As for the error that it's already running: docker stop mosquitto && docker rm mosquitto before running again the container.

    Somo


    Tried Cat no such file or directory see below



    Code
    $ cat /home/mike/docker-mosquitto/mosquitto/config/mosquitto.conf
cat: /home/mike/docker-mosquitto/mosquitto/config/mosquitto.conf: No such file or directory
$ docker run -it --name mosquitto -p 1883:1883 -v /home/mike/docker-mosquitto/mosquitto/config:/mosquitto/config/ -v /home/mike/docker-mosquitto/mosquitto/data:/mosquitto/data/ -v /home/mike/docker-mosquitto/mosquitto/log:/mosquitto/log/ eclipse-mosquitto
1620222691: Error: Unable to open config file /mosquitto/config/mosquitto.conf.
$ docker stop mosquitto && docker rm mosquitto
mosquitto
mosquitto
    Code
    ls -al /home/mike/docker-mosquitto/mosquitto.config       
ls: cannot access '/home/mike/docker-mosquitto/mosquitto.config': No such file or directory

    it looks as though i am not in the incorrect directory

    ls -al /home/mike/docker-mosquitto/mosquitto/config <<<<<----- This the command I gave you



    Zitat von MIkey6283

    ls -al /home/mike/docker-mosquitto/mosquitto.config

    You're putting a DOT . where it's a SLASH /

    Just a remark: you're logged as "mike", correct???


    Ok, now run nano /home/mike/docker-mosquitto/mosquitto/config/mosquitto.conf


    And then copy/paste this:

    Code
    # following two lines required for > v2.0
allow_anonymous true
listener 1883
persistence true
persistence_location /mosquitto/data/
log_dest file /mosquitto/log/mosquitto.log

    Click Ctrl + X and then Y


    Now try again the cat /home/mike/docker-mosquitto/mosquitto/config/mosquitto.conf


    And then run the docker.

    error in nano Permission denied

    I checked to make sure to see which directory i was in and this is mike on my external ssd ?? Does this mean that i have the files on the ssd ?


    $ pwd

    /srv/dev-disk-by-uuid-e67cf220-d53c-4dfc-85db-41d8d6db235c/one/mike/docker-mosquitto

    $

    I pwd to see which directly i was in and ls result below

    Code
    $ nano /home/mike/docker-mosquitto/mosquitto/config/mosquitto.conf
$ pwd
/srv/dev-disk-by-uuid-e67cf220-d53c-4dfc-85db-41d8d6db235c/one/mike/docker-mosquitto
$ ls  
mosquitto
$ ls
