It is focusing on essential and cEOS-lab specific features. Please check [Containerlab documentation](https://containerlab.srlinux.dev/) for more details. + +--- + +# How To Run The Workshop + + + +To run the labs in this workshop, you can use one of the following options: + +- Build you own Ubuntu VM from scratch. (Recommended!) + - This option will allow you to experience the entire cLab enviroment build process from the very start, without any pre-installed dependancies + - Requirements + - Ubuntu LTS 22.04 or later + - 8 GB RAM and 4 vCPUs +- Start the [Github Codespace](https://codespaces.new/{{gh.repository}}?quickstart=1&devcontainer_path=.devcontainer%2Fclab-build-containerlab-with-ceos%2Fdevcontainer.json) from this repository. (Fastest!) +- Open the lab dev container locally on your laptop with Docker Desktop or sever with Docker CE: + - you can [download required files here](https://arista-netdevops-community.github.io/one-click-se-demos/lab_archives/clab-build-containerlab-with-ceos.tar.gz) and open them in VSCode + - when running the lab locally, you must set all required environment variables on your machine + +--- + +# CPU Architechture + +- Only x86 CPU architecture is supported! +- It is technically possible to [run Container lab on ARM](https://containerlab.dev/install/#containerlab-on-arm-based-macs), but there are no network device images available for ARM as of May 2024. + +--- + +# Setup Docker on the Host + + + +
+
+ +> Check if Docker is already installed. In this case you can skip the steps below. + +1. Install Docker on the host. The detailed instructions are available [here](https://docs.docker.com/engine/install/ubuntu/). You can used one-liner script for that. +2. Add your user to the `docker` group. +3. Logout and login again to apply the changes. +4. Check the Docker version and run `hello-world` container to test functionality. +5. You must be able to run `docker` commands without `sudo` if it was installed correctly. + +
+
+ +```bash +# install Docker +sudo curl -fsSL https://get.docker.com | sh +# add user to the docker group +sudo usermod -aG docker ${USER} +# test docker +docker --version +docker run hello-world +``` + +> **NOTE**: If you are running this workshop in Codespace or provided dev container, Docker is pre-installed. As the workshop magic happens inside a container in this case, we rely on Docker-in-Docker concept to provide required functionality. + +
+
+ +--- + +# Setup Git (Optional) + + + +- Git must be pre-installed on a Linux system. Otherwise you are in a wrong place. Escape! 👾 🚀 +- Setup your name and email address: + + ```bash + git config --global user.name "" + git config --global user.email "" + ``` + +- Check the current configuration: + + ```bash + git config --list + ``` + +> **NOTE**: On Codespace Git is pre-installed and pre-configured. + +--- + +# Download cEOS-lab Image + + + +1. Login to [Arista Software Download](https://www.arista.com/en/support/software-download) portal. You need to have an account to download the image. +2. Select `EOS > Active Releases > 4.30 > EOS-4.30.6M > cEOS-lab`. +3. Download `cEOS-lab-4.30.6M.tar.xz` image. +4. Upload the image to your lab VM. For example, you can use SFTP to transfer the image: + + ```bash + sftp ${REMOTE_USER}@${UBUNTU_VM_IP}:/home/${REMOTE_USER}/${IMAGE_DIR} <<< $'put cEOS-lab-4.30.6M.tar*' + # for example: + # sftp user@10.10.10.11:/home/user/images <<< $'put cEOS-lab-4.30.6M.tar*' + ``` + +> If Github Codespace or provided Dev Container is used and the Arista token is set, the image will be pulled from arista.com automatically. + +![bg right h:720](img/clab-build-containerlab-with-ceos/ceos-lab-download.png) + +--- + +# Import cEOS-lab Image + + + +1. Go to the directory with the uploaded image and import the image: + + ```bash + docker import cEOS-lab-4.30.2F.tar.xz ceos-lab:4.30.2F + ``` + + > NOTE: you can also import the image with the tag latest to allow quick "upgrade" of those lab where specific version is not required: `docker tag ceos-lab:4.30.2F ceos-lab:latest` + +2. Confirm that the image was imported successfully: + + ```console + $ docker image ls + REPOSITORY TAG IMAGE ID CREATED SIZE + ceos-lab 4.30.2F 21b540a4a343 45 minutes ago 1.95GB + ceos-lab latest 21b540a4a343 45 minutes ago 1.95GB + hello-world latest b038788ddb22 3 months ago 9.14kB + ``` + +--- + +# Install Containerlab + -![bg right opacity:75%](img/pexels-suzy-hazelwood-1226398.jpg) +- It's just a one-liner: + + ```bash + bash -c "$(curl -sL https://get.containerlab.dev)" + ``` + +- Refer to the [Containerlab quick start documentation](https://containerlab.dev/quickstart/) for the details. + +--- -- item1 -- item2 -- item3 +to-be-defined --- -![bg left opacity:75%](img/pexels-ann-h-7186206.jpg) +![bg left opacity:80%](img/pexels-ann-h-7186206.jpg) # Q&A -- [Ansible AVD](https://avd.arista.com/) +- [Containerlab](https://containerlab.srlinux.dev/) - [This repository](https://github.com/{{gh.repository}}) diff --git a/slides/img/clab-build-containerlab-with-ceos/containerlab_export_white_ink.svg b/slides/img/clab-build-containerlab-with-ceos/containerlab_export_white_ink.svg new file mode 100644 index 0000000..c26dfc6 --- /dev/null +++ b/slides/img/clab-build-containerlab-with-ceos/containerlab_export_white_ink.svg @@ -0,0 +1 @@ + \ No newline at end of file
