In the preferences, impossible to make communicate gns3 with vmware to load IOS to GNS3 VM. Do you have a procedure?

there's a way to update the image or you need to push it?

Hello,
I'm not sure if it's something wrong with my system, but I get python errors:

I know it's not a problem with this repo.

However, I opened an issue because it can be resolved simply by updating the dockerfile until the next version is released.

FROM alpine:3.19.1

# Install the magic wrapper.
ADD ./start.sh /start.sh
ADD ./config.ini /config.ini
ADD ./requirements.txt /requirements.txt
COPY dependencies.json /tmp/dependencies.json

RUN mkdir /data && \
    apk add --no-cache --virtual=build-dependencies jq gcc python3-dev musl-dev linux-headers \
    && jq -r 'to_entries | .[] | .key + "=" + .value' /tmp/dependencies.json | xargs apk add --no-cache \
    && pip install -r /requirements.txt --break-system-packages \
    && apk del --purge build-dependencies

CMD [ "/start.sh" ]

# this new line!!
RUN ln -s /bin/busybox /usr/lib/python3.11/site-packages/gns3server/compute/docker/resources/bin
WORKDIR /data

VOLUME ["/data"]

This temporarily resolves the issue of Docker not running.

I'm trying to start an appliance on the gn3-server but it returns me this error

KVM acceleration cannot be used (/dev/kvm doesn't exist). It is possible to turn off KVM support in the gns3_server.conf by adding enable_kvm = false to the [Qemu] section.

Hello,

I am unable to load the gn3 container by using docker on a remote machine. When I try to launch the server web page, I get nothing "site can't be reached" error on the browser. eg http://192.168.3.50:3030 - nothing opens up.

Expected response: should be able to open up GNS3 on a remote site using a custom port (3080 or any other)

This is my docker compose file:

services:
    gns3-server:
      image: jsimonetti/gns3-server:latest
      container_name: gns3
      privileged: false

      volumes:
       - ./data:/data
      network_mode: host

Log file attached
gns3logs.txt
From the logs, it looks like this is the culprit:

Hi, do you know how to run your container through a proxy, in my case traefik. I get Configuration error - 'network_mode' and 'networks' cannot be combined"

Here my docker-compose.yml

networks:
  traefik-00:
    name: traefik-00
    external: true

services:
  gns3-server:
    container_name: gns3-server
    hostname: gns3.domain.tld
    image: jsimonetti/gns3-server:latest 
    privileged: true
    restart: always
    environment:
      - BRIDGE_ADDRESS="172.21.1.1/24"
    labels:
      - traefik.enable=true
      - traefik.backend=gns3.domain.tld
      - traefik.frontend.rule=Host:gns3.domain.tld
      - traefik.docker.network=traefik-00
    network_mode: "host"
    networks:
      - traefik-00
    expose:
      - "3080"
    volumes:
      - ./data:/data

Thanks in advance,

Hello, I'm relatively new to Docker so forgive me if this is a dumb question. I'd like to be able to configure username and password when I create the container. I've got an automated setup that will be creating these containers so I'd like to do it from the Docker API rather than having to manually enter the container and edit the config. Is this possible?

Thank you so much for this project, btw! It's been a huge help.

Although is not a problem I would like to post a possible future improvement.
Wireshark is not installed with the GNS3 container.
I would like to ask you to include Wireshark if possible.
Also, I have installed the gns3-gui with python in the host to use it instead the webUI.
However, projects are not saved in /GNS3/projects, they are saved inside the container.
May I ask you to include some information in the README to configure the folder to save projects in host.
I want to thank you to make public your docker image of GNS3 server.

Recently pulled the latest image. Looks like it fails to startup.

Just an FYI,
Issue appears to be in gns3server itself, so I'll look closely and open a bug on their github.

Hello,

2.2.25 client is out but sadly I can't use it since the gns3-server image on Docker Hub is 2.2.22

Help?
Thanks!

Connecting to a docker container running the latest image will return the following error;
Client version 2.2.17 is not the same as server (controller) version 2.2.15

Could you please update the server version to 2.2.17? Thank you!

Hello,

The docker-gns3-server is very nice, want to explore the possibility to add IOU support.

I use IOS on GNS3-VM or docker without issue, only IOU on docker doesn't work, some of the command to check the file or environment from both as below

on GNS3 VM
Use file command to check the IOU file type
/opt/gns3/images/IOU$ file i86bi-linux-l2-adventerprise-15.1b.bin
i86bi-linux-l2-adventerprise-15.1b.bin: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.2.5, stripped

use ldd command to check the required share library
/opt/gns3/images/IOU$ ldd i86bi-linux-l2-adventerprise-15.1b.bin
linux-gate.so.1 (0xf7fc0000)

libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0xf79ba000)
/lib/ld-linux.so.2 (0xf7fc2000)

Use ls command to check the shared library for i386 arch, all the required library are there.

on docker-gns3-server
when start IOU, it said Invalid IOU license key detected in iourc file /data/.iourc
the command (same as gns3-VM) output as below:
file command
/home/azureuser/gns3/images/IOU# file i86bi-linux-l3-adventerprisek9-15.4.1T.bin

comments: it’s the same as GNS3-VM

ldd command
/home/azureuser/gns3/images/IOU# ldd i86bi-linux-l3-adventerprisek9-15.4.1T.bin
not a dynamic executable
comments: it seems lack of necessary i386 arch shared library

use find command didn’t found the i386 shared libraries.

I’m thinking if the docker missing the i386 shared library which can be further update the docker or it’s intend not to supportIOU at all.

The intention is have the gns3 server running on azure cloud, so I can access the test environment anywhere and anytime.

not sure this should be a feature request or issue. thanks a lot.

Hi,

Dear Jeroen Simonetti,

I used successfully a pervious image "sha256: 4fd4df58677926fa38c414aab9e2af8a9c5752b242493c8b305041876ebc3ac7", but after updating to the latest, it fails with some python error. This is the log:
