Landscape2 is a tool that generates interactive landscapes websites.
You can check out how the generated landscapes look like by visiting the CNCF landscape. Additional landscapes generated by this tool can be found in the landscape2-sites repository.
Warning
Landscape2 is at an early stage of development. There may be breaking changes in the future to the command usage, flags, and configuration file formats.

Landscape2 is a CLI tool that generates static websites from the information available in the data sources provided. These data sources are passed to the tool via arguments, usually in the form of urls or local paths, and are as follows:
-
Landscape data. The landscape data file is a YAML file that describes the items that will be displayed in the landscape website. For backwards compatibility reasons, this file must follow the format and conventions defined in the CNCF landscape.yml file.
-
Landscape settings. The settings file is a YAML file that allows customizing some aspects of the generated landscape website, such as the logo, colors, how to group items or which ones should be featured. For more information about the settings file, please see the reference documentation.
-
Landscape guide. The guide file is a YAML file that defines the content of the guide that will be displayed on the landscape website. For more information, please see the reference documentation.
-
Logos location. Each landscape item must provide a valid relative reference to a logo image in SVG format in the landscape data file (item's
logofield). The logos data source defines the location of those logos (base url or local path), so that the tool can get them as needed when processing the landscape items.
In addition to the information available in the landscape data file, the tool collects more data during the landscape generation from external sources (such as GitHub or Crunchbase) if the required credentials are provided. These credentials must be provided via environment variables.
-
GitHub: a list of comma separated GitHub tokens with
public_reposcope can be provided in theGITHUB_TOKENSenvironment variable. When these tokens are not provided no information from GitHub will be collected. If the expected number of items in the landscape is large it is recommended to provide more than one token to avoid hitting rate limits and speed up the collection of data (the concurrency of the process will be based on the number of tokens provided). -
Crunchbase: a Crunchbase API key can be provided in the
CRUNCHBASE_API_KEYenvironment variable. If this token is not provided no information from Crunchbase will be collected.
Binary downloads of the landscape2 CLI tool can be found in the releases page.
brew install cncf/landscape2/landscape2
curl --proto '=https' --tlsv1.2 -LsSf https://github.com/cncf/landscape2/releases/download/v0.7.0/landscape2-installer.sh | sh
irm https://github.com/cncf/landscape2/releases/download/v0.7.0/landscape2-installer.ps1 | iex
The landscape2 CLI tool is also distributed in a container image. This image can be used both to run the tool locally or from your CI workflows to automate the generation of landscapes. The landscape2-validate-action, which can be used to check that the landscape data, settings and guide files are valid, also uses this image.
You can build landscape2 from the source by using Cargo, the Rust package manager. yarn is required during the installation process to build the web application, which will be embedded into the landscape2 binary as part of the build process.
cargo install --git https://github.com/cncf/landscape2
landscape2 --help
Landscape2 CLI tool
https://github.com/cncf/landscape2#usage
Usage: landscape2 <COMMAND>
Commands:
build Build landscape website
deploy Deploy landscape website (experimental)
new Create a new landscape from the built-in template
serve Serve landscape website
validate Validate landscape data sources files
help Print this message or the help of the given subcommand(s)
To see landscape2 in action, we will go through the process of creating, building and serving a new landscape from scratch. The following instructions will assume that the landscape2 binary is available in your PATH. Alternatively, you can launch a container from the image provided where the landscape2 CLI tool is ready to use.
The new subcommand allows us to create a new landscape from a built-in template. This template includes some sample data source files that you can use as a starting point for your landscapes.
The following command will create the directory my-landscape if it doesn't already exist and will copy into it the files in the built-in template:
landscape2 new --output-dir my-landscape
INFO new: landscape2::new: creating new landscape from the built-in template..
INFO new: landscape2::new: landscape created! (took: 0.003s)
✅ Landscape created successfully!
You can build it by running the following command from the `my-landscape` directory:
👉 landscape2 build --data-file data.yml --settings-file settings.yml --guide-file guide.yml --logos-path logos --output-dir build
The build process is in charge of generating the landscape website from the information available in the data sources provided. Now we'll build the landscape we created in the previous step by using the build subcommand. Please note that the new subcommand already suggested us to do this in its output and even printed the full command to use for us.
Note
During the build process, landscape2 will try to take a screenshot of your landscape if the required settings were provided in the settings.yml file. This screenshot will be available for download from the generated web application (in PNG and PDF format), and is taken by launching Chrome/Chromium in headless mode. If Chrome/Chromium is not available, the screenshot won't be taken and a warning will be raised.
The following command will build the landscape and write the resulting files to the output-dir provided (build in this case):
cd my-landscape
landscape2 build \
--data-file data.yml \
--settings-file settings.yml \
--guide-file guide.yml \
--logos-path logos \
--output-dir build
INFO build: landscape2::build: building landscape website..
WARN build:collect_crunchbase_data: landscape2::build::crunchbase: crunchbase api key not provided: no information will be collected from crunchbase
WARN build:collect_github_data: landscape2::build::github: github tokens not provided: no information will be collected from github
INFO build: landscape2::build: landscape website built! (took: 0.555s)
✅ Landscape built successfully!
You can see it in action by running the following command:
👉 landscape2 serve --landscape-dir build
Important
Without the credentials required to collect data from external services (GitHub and Crunchbase) the resulting site won't contain all the information available on the CNCF demo site. In this case, we didn't provide them intentionally, so we were warned about it in the command output (see WARN entries).
The result of the build process is a static website that you can deploy on your favorite hosting provider. To make it easier to try your landscapes, landscape2 includes a serve subcommand that will launch an HTTP server and serve the contents of your landscape. In our example, the build output displayed the command to do this, so we'll go ahead and give it a try:
landscape2 serve --landscape-dir build
INFO serve: landscape2::serve: http server running (press ctrl+c to stop)
🔗 Landscape available at: http://127.0.0.1:8000
If you visit http://127.0.0.1:8000 in your browser you should see the landscape you just created in action. Now you can iterate by editing the files in the my-landscape directory until your landscape is ready.
Note
The resulting website when building a landscape is a single-page application that handles routing on the client side. This means that you'll need to configure your webserver to serve the index.html file for the SPA route paths (like '/guide', '/stats', etc). One way of doing this would be to serve that file when a non existent path is requested. The serve subcommand included in landscape2 already handles this for us.
The landscape2 CLI tool includes a subcommand named validate that allows you to check that your landscape data, settings and guide files are valid. If you are interested in integrating this validation in your CI workflows (i.e. to enforce that those files are valid before merging a PR), please take a look at the landscape2-validate-action.
landscape2 validate settings --settings-file cncf/settings.yml
Error: the landscape settings file provided is not valid
Caused by:
0: the landscape settings file provided is not valid
1: color1 is not valid (expected format: "rgba(0, 107, 204, 1)")
Some operations like collecting data from external sources or processing a lot of logos images can take some time, specially in landscapes with lots of items. Landscape2 caches as much of this data as possible to make subsequent runs faster. Please keep this in mind when running the tool periodically from your workflows, and make sure the cache directory (set via --cache-dir) is saved and restored on each run. You can find some examples of how to achieve this in the workflows in the landscape2-sites repository.
Landscape2 allows other websites to embed a view to display the items in a category or subcategory. The embed code can be easily obtained from the corresponding landscape website by visiting /embed-setup (i.e. in the case of the CNCF landscape, the url would be https://landscape.cncf.io/embed-setup). The customization options available can be adjusted as needed, and the generated embed code will be updated accordingly.
Note
In addition to the customization options available in the embed setup view, it's also possible to embed views using iframe-resizer. This feature can be enabled by adding iframe-resizer=true to the embed url (demo).
A list of landscapes built using landscape2 is available at ADOPTERS.md. Please consider adding yours!
