## Ubuntu Desktop (GNOME 3) Dockerfile


This repository contains the *Dockerfile* and *associated files* for setting up a container with Ubuntu, GNOME 3, TigerVNC and noVNC.

* The VNC Server currently defaults to 1366*768 24bit.

### Dependencies

* [ubuntu:20.04](https://hub.docker.com/_/ubuntu)


### Usage

#### Container actions

* Start container:

      sudo docker run --name=ubuntu-gnome -d --rm \
        --tmpfs /run --tmpfs /run/lock --tmpfs /tmp \
        --cap-add SYS_BOOT --cap-add SYS_ADMIN \
        -v /sys/fs/cgroup:/sys/fs/cgroup \
        -p 5901:5901 -p 6901:6901 \
        darkdragon001/ubuntu-gnome-vnc

* Open (root) shell:

      sudo docker exec -it ubuntu-gnome bash

* Open shell as user:

      sudo docker exec -it -u default ubuntu-gnome bash

* Stop container:

      sudo docker stop ubuntu-gnome

#### Connecting to instance

* Connect to `vnc://<host>:5901` via your VNC client.
* Connect to `http://<host>:6901` via your web browser.

_**NOTE** The password is hardcoded to `acoman`._

#### Using the desktop

* Gain root access via `sudo`


### Known issues

* Sidebar/dock hidden by default
* User switching / gdm3 not working

### Not tested

* Sound (PulseAudio)


### Dee
如果要 VNC 不要那么多权限启动 （因为现在要宿主机的权限过多）

* 可以先设置docker内访问dbus：https://georgik.rocks/how-to-start-d-bus-in-docker-container/
* Ubuntu：
    
    dbus-uuidgen > /var/lib/dbus/machine-id

    mkdir -p /var/run/dbus

    dbus-daemon --config-file=/usr/share/dbus-1/system.conf --print-address


*    再 vncserver 启动时 。带参数 （带上 localhost no 那一串，如果加 会启动不了）
    如：
    /usr/bin/vncserver :1 -geometry 1366x768 -depth 24 -localhost no -fg

    启动指令可以简化为：
    docker run -it --rm xxx:tag /bin/bash
