Ubuntu Docker Container

Is it possible to install ubuntu as a docker container?

If so then how can i do it?

What i already tried is that i downloaded the ubuntu docker image and started the docker in the command line with

docker run -d -t -p 6000:6000 --name ubuntu_container ubuntu

The container started succesfully but i cannot acces the gui.

What can i do to access the gui as a normal ubuntu system?

--------------------------------------------------------------------------------------------

I don't have much experience with ubuntu as a docker container

I would appreciate help

Sorry for my missunderstanding

dockers are not Virtual Machines, to do a ubuntu install, better to install first KVM ( A VM GUI) and then install ubuntu like a VM.

I know this, it is just i would like to install a matrix/synapse container on my arm system but they don't support it anymore.

So my playful attempt was to maybe have a little container running a form of linux and then install the matrix/synapse container onto the linux container.

Kind of confusing but i hope i made it clear enough.

It was just a playful attempt if something like that would be possible.

So actually i would not need a full gui

Are you looking for this one? https://hub.docker.com/r/matrixdotorg/synapse

There are a few older arm v7 builds, butthe newer ones are for arm64.

Yes i mean exactly this one.

I didn't know that i could still use the older versions

Zitat von Soma

What I understood, is: you want to run x86_64 app under an arm equipment, is that it?

i have arm32

yes if possible i guess

Zitat von Zoki

use image: matrixdotorg/synapse:v1.26.0-deb

or build your own image.

Yeah i guess i will use a older tag or build my own image if needed

Zitat von Soma

No.

If there's an arm64 version for the container you want, you'll have to move the whole system to arm64.

The docker will always download only the image version for the same architecture of the Host.

Even if you bypass it with a TAG for other architectures, the container will error.

You can follow Zoki advice and use an old image TAG that has arm32 support.

Something like:

docker pull ccrisan/motioneye:master-armhf

Yeah you are right. True.

I will follow Zokis suggestion.

Thanks for all the help!

Sorry for bothering again.

I am currently on installing the matrix synapse container.

Based on the file generation basic command

docker run -it --rm \
    --mount type=volume,src=synapse-data,dst=/data \
    -e SYNAPSE_SERVER_NAME=my.matrix.host \
    -e SYNAPSE_REPORT_STATS=yes \
    matrixdotorg/synapse:latest generate

i want to change the paths.

docker run -it --rm \
    --mount type=volume,src=synapse-data,dst=/data \
    -e SYNAPSE_SERVER_NAME=my.subdomain.com \
    -e SYNAPSE_REPORT_STATS=no \
    -e SYNAPSE_HTTP_PORT=8008 \
    -e SYNAPSE_CONFIG_DIR=/var/lib/config/elements \
    -e SYNAPSE_CONFIG_PATH=/var/lib/config/elements/homeserver.yaml \
    -e SYNAPSE_DATA_DIR=/var/lib/config/elements \
    -e UID=1004
    -e GID=100
    matrixdotorg/synapse:v1.26.0-deb generate

I did it like the instructions say but i wonder if i also have to edit the above

src=synapse-data,dst=/data

Do i think wrong and everything is right or should i also change the src and dist criteria?

And if so then how should i adjust them

Zitat von Zoki

ou need to change quite a bit:

the mount requires a docker volume, do you want this or do you want to mount an existing directory into the container?
the environment vars point to /var/lib/... which is somewhere in the container and will be lost when you recreate the container
Leave them default
UID and GID should be the user you created as per the tutorial.
-e SYNAPSE_SERVER_NAME=my.subdomain.com this is most likely not your domain name

mhm..ok

i am trying a bit.

I first want to do a basic install and if it works i will modify the paths etc
