I am using an Appium service to automate a flutter application on Android. I was able to connect to my host’s ADB and install Appium Settings and the flutter application. But I was not able to connect to AndroidUiautomator2Driver as shown in the logs below:

[ADB] Running '/usr/lib/android-sdk/platform-tools/adb -P 5037 -s RR8W802EFNN install -r -g /home/myuser/app-debug.apk'

And this is how I configure the environment in my Dockerfile:

RUN apt-get update  
    && yes | apt-get install -y maven  
    && yes | apt-get install usbutils 
    && apt install wget 
    && yes | apt-get install android-sdk 
    && yes | apt-get install android-tools-adb 
    && apt clean  
    && rm -rf /var/lib/apt/lists/*


ENV ANDROID_HOME "/usr/lib/android-sdk"
ENV ANDROID_SDK_ROOT $ANDROID_HOME
ENV PATH $PATH:$ANDROID_HOME/platforms:$ANDROID_HOME/tools/bin:$ANDROID_HOME/platform-tools:$ANDROID_HOME/build-tools
ENV ANDROID_ADB_SERVER_ADDRESS "host.docker.internal"


RUN useradd -ms /bin/bash myuser 
    && usermod -aG root myuser

USER myuser

SHELL ["/bin/bash", "--login", "-c"]

RUN curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash 
    && source $HOME/.nvm/nvm.sh 
    && nvm install v16.18.1 
    && npm install -g appium@latest 
    && appium driver install uiautomator2  
    && appium driver install xcuitest  
    && appium driver install --source=npm appium-flutter-driver  
    && appium plugin install relaxed-caps  
    && appium plugin install execute-driver 
    && appium plugin install --source=npm appium-wait-plugin

And this is how my compose.yml look like:

services:
  service:
    image: image
    network_mode: host
    hostname: localhost
    volumes:
      - /Users/.m2:/home/myuser/.m2

I even tried to curl to http://127.0.0.1:8200 on the container, and was Connection refused. But when I curl from my laptop it works fine. I do not understand what am I doing wrong. Since the network_mode is set to host, the container should be able to connect to any localhost port no? How can I make this work?

The issue you are experiencing is probably a docker network issue.
Try updating your dockerfile :

FROM openjdk:11-jdk-slim

RUN apt-get update && apt-get install -y 
    wget curl unzip android-tools-adb 
    && rm -rf /var/lib/apt/lists/*

ENV ANDROID_HOME /opt/android-sdk
ENV PATH ${PATH}:${ANDROID_HOME}/tools:${ANDROID_HOME}/platform-tools

RUN mkdir -p ${ANDROID_HOME} && cd ${ANDROID_HOME} 
    && wget https://dl.google.com/android/repository/commandlinetools-linux-7583922_latest.zip 
    && unzip commandlinetools-linux-7583922_latest.zip 
    && rm commandlinetools-linux-7583922_latest.zip 
    && yes | sdkmanager --licenses 
    && sdkmanager "platform-tools" "platforms;android-30" "build-tools;30.0.3"

RUN curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash 
    && . $NVM_DIR/nvm.sh 
    && nvm install 16.18.1 
    && npm install -g appium@latest 
    && appium driver install uiautomator2 flutter 
    && appium plugin install relaxed-caps execute-driver appium-wait-plugin

CMD ["appium", "--allow-insecure", "chromedriver_autodownload"]

And your docker compose :

version: '3'
services:
  appium:
    build: .
    privileged: true
    network_mode: host
    environment:
      - ANDROID_ADB_SERVER_ADDRESS=host.docker.internal
    volumes:
      - /dev/bus/usb:/dev/bus/usb
      - ~/.m2:/home/appuser/.m2
    ports:
      - "4723:4723"

Ensure your device is connected and visible in ADBm then build and run the docker compose to see if the issue is resolved

Verify Appium configuration to ensure it is set up to use the correct
port and IP address for the AndroidUiautomator2Driver
Even with network_mode: host, ensure that no firewall or security
group settings on your host or Docker daemon are blocking the
connection.
You may need to adjust the Appium server’s binding settings to make
sure it is accessible on 0.0.0.0.

If this not solve your issue try to change the docker file

Update your Dockerfile

RUN apt-get update 
    && apt-get install -y maven usbutils wget android-sdk android-tools-adb 
    && apt-get clean 
    && rm -rf /var/lib/apt/lists/*

ENV ANDROID_HOME="/usr/lib/android-sdk"
ENV ANDROID_SDK_ROOT=$ANDROID_HOME
ENV PATH=$PATH:$ANDROID_HOME/platform-tools

RUN useradd -ms /bin/bash myuser 
    && usermod -aG root myuser

USER myuser

RUN curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash 
    && source $HOME/.nvm/nvm.sh 
    && nvm install v16.18.1 
    && npm install -g appium@latest 
    && appium driver install uiautomator2 
    && appium driver install xcuitest 
    && appium driver install --source=npm appium-flutter-driver 
    && appium plugin install relaxed-caps 
    && appium plugin install execute-driver 
    && appium plugin install --source=npm appium-wait-plugin

and docker-compose.yml

version: '3'
services:
  service:
    image: image
    network_mode: host
    hostname: localhost
    volumes:
      - /Users/.m2:/home/myuser/.m2
    environment:
      - ANDROID_ADB_SERVER_ADDRESS=host.docker.internal

Set ANDROID_ADB_SERVER_ADDRESS to host.docker.internal to ensure
the container can communicate with the host’s ADB server.
