Docker in windows

Concept

Docker is a popular tool that allows developers to easily create, deploy, and run applications in containers. However, some users may experience slow performance when using Docker on Windows. In this blog post, we will explore several ways to improve the performance of Docker on Windows and make your development workflow more efficient.

1. Enable the use of the Windows Subsystem for Linux (WSL) 2

The Windows Subsystem for Linux (WSL) is a compatibility layer for running Linux binaries natively on Windows. By enabling WSL 2, you can improve the performance of running Linux containers on Windows. To enable WSL, navigate to Settings > Resources > WSL and select the option to “Enable WSL”.

2. Configure Memory and CPU Resources

Docker for Windows allows you to configure the amount of memory and CPU resources allocated to the Docker daemon. By increasing the resources allocated to the Docker daemon, you can improve the performance of your containers. To access these settings, navigate to the Docker for Windows settings menu and select the “Advanced” tab.

3. Use a Fast Disk Image Location

Docker for Windows allows you to configure the location of the disk image used by the Docker daemon. By default, the disk image is stored on the same drive as the Windows operating system. However, if you have a fast SSD drive, you can configure the disk image location to this drive to improve performance. To access this setting, navigate to the Docker for Windows settings menu and select the “Docker Daemon” tab.

4. Use a Container Orchestration Tool

Container orchestration tools like Docker Compose or Kubernetes can help improve the resource utilization and performance of your containers. These tools allow you to easily manage multiple containers and configure resources such as memory and CPU usage.

5. Use the –mount Flag

When running a container, you can use the –mount flag to mount the host machine’s filesystem to the container. This allows data to be stored on the host machine rather than within the container, which can improve performance.

6. Keep your Windows updated and use the latest version of Docker

Make sure you keep your Windows updated and use the latest version of Docker for Windows to take advantage of performance improvements and bug fixes.

In conclusion, while Docker is a powerful tool, some users may experience slow performance when using it on Windows. By following the tips outlined in this blog post, you can improve the performance of your containers and make your development workflow more efficient. Remember, the performance of your containers will also be affected by the performance of the underlying host machine, so make sure that your system meets the minimum requirements for running Docker.

Issues that i saw while setup

1. System has not been booted with systemd as init system (PID 1).

Can’t operate. Failed to connect to bus: Host is down

try:

sudo apt-get update && sudo apt-get install -yqq daemonize dbus-user-session fontconfig

sudo daemonize /usr/bin/unshare --fork --pid --mount-proc /lib/systemd/systemd --system-unit=basic.target

exec sudo nsenter -t $(pidof systemd) -a su - $LOGNAME

2. docker.credentials.errors.InitializationError:

docker-credential-desktop.exe not installed or not available in PATH
[519] Failed to execute script docker-compose

rm ~/.docker/config.json

3. Connection reset by peer on systemctl

sudo apt update
sudo apt install -y git
git clone https://github.com/DamionGans/ubuntu-wsl2-systemd-script.git
cd ubuntu-wsl2-systemd-script/
bash ubuntu-wsl2-systemd-script.sh

4. ERROR: An HTTP request took too long to complete.
