Get familiar with Kosli #

The following guide is the easiest and quickest way to try Kosli out and understand its features. It is made to run from your local machine, but the same concepts and steps apply to using Kosli in a production setup.

In this tutorial, you'll learn how Kosli allows you to follow a source code change to runtime environments. You'll set up a docker environment, use Kosli to record build and deployment events, and track what artifacts are running in your runtime environment.

This tutorial uses the docker Kosli environment type, but the same steps can be applied to other supported environment types.

As you go through the guide you can also check your progress from your browser.

In the upper left corner there is a house icon. Next to it you can select which organization you want to view. Your personal organization has the same name as your github login name, and is the organization you will be using in this guide.

Step 1: Prerequisites and Kosli account #

To follow the tutorial, you will need to:

  • Install both Docker and docker-compose.

  • Create a Kosli account if you have not got one already.

  • Install Kosli CLI.

  • Get a Kosli API token.

  • Set the KOSLI_ORG and KOSLI_API_TOKEN environment variables:

    export KOSLI_ORG=<your-org>
    export KOSLI_API_TOKEN=<your-api-token>
    
  • You can check your Kosli set up by running:

    kosli list flows
    

    which should return a list of flows or the message "No flows were found".

  • Clone our quickstart-docker repository:

    git clone https://github.com/kosli-dev/quickstart-docker-example.git
    cd quickstart-docker-example
    

Step 2: Create a Kosli Flow #

The Flow's yml template-file exists in the git repository. Confirm this yml file exists by catting it:

cat kosli.yml

You will see the following output, specifying the existence of an Artifact named nginx:

version: 1

trail:
  artifacts:
    - name: nginx

Create a Kosli Flow called quickstart-nginx using this yml template-file:

kosli create flow2 quickstart-nginx \
    --description "Flow for quickstart nginx image" \
    --template-file kosli.yml

Confirm the Kosli Flow called quickstart-nginx was created:

kosli list flows

which will produce the following output:

NAME              DESCRIPTION                          VISIBILITY
quickstart-nginx  Flow for quickstart nginx image      private
In the web interface you can select Flows on the left. It will show you that you have a quickstart-nginx Flow. If you select the Flow it will show that no Artifacts have been reported yet.

Step 3: Create a Kosli Trail #

Create a Kosli Trail, in the quickstart-nginx Flow, whose name is the repository's current git-commit:

GIT_COMMIT=$(git rev-parse HEAD)
kosli begin trail ${GIT_COMMIT} \
    --flow quickstart-nginx

Step 4: Create a Kosli environment #

Create a Kosli Environment called quickstart whose type is docker:

kosli create environment quickstart \
    --type docker \
    --description "quickstart environment for tutorial"

You can verify that the Kosli Environment was created:

kosli list environments
NAME        TYPE    LAST REPORT  LAST MODIFIED
quickstart  docker               2022-11-01T15:30:56+01:00
If you refresh the Environments web page in your Kosli account, it will show you that you have a quickstart environment and that no snapshot reports have been received yet.

Step 5: Attest an Artifact to Kosli #

Typically, you would build an Artifact in your CI system, in response to a git-commit. The quickstart-docker repository contains a docker-compose.yml file which uses an nginx docker image which you will be using as your Artifact in this tutorial instead.

Pull the docker image - the Kosli CLI needs the Artifact to be locally present to generate a "fingerprint" to identify it:

docker-compose pull

You can check that this has worked by typing:

docker images nginx

The output should look like this:

REPOSITORY   TAG       IMAGE ID       CREATED        SIZE
nginx        1.21      8f05d7383593   5 months ago   134MB

Now report the artifact to Kosli using the kosli attest artifact command.

Note:

  • The --name flag has the value nginx which is the (only) artifact name defined in the kosli.yml file from step 2.
  • The --build-url and --commit-url flags have dummy values; in a real call these would get default values (e.g. from Github Actions).
GIT_COMMIT=$(git rev-parse HEAD)
kosli attest artifact nginx:1.21 \  
    --name nginx \
    --flow quickstart-nginx \
    --trail ${GIT_COMMIT} \
    --artifact-type docker \
    --build-url https://example.com \
    --commit-url https://github.com/kosli-dev/quickstart-docker-example/commit/9f14efa0c91807da9a8b1d1d6332c5b3aa24a310 \
    --git-commit $(git rev-parse HEAD)    

You can verify that you have reported the Artifact in your quickstart-nginx flow:

kosli list artifacts --flow quickstart-nginx
COMMIT   ARTIFACT                                                                       STATE      CREATED_AT
9f14efa  Name: nginx:1.21                                                               COMPLIANT  Tue, 01 Nov 2022 15:46:59 CET
         Fingerprint: 2bcabc23b45489fb0885d69a06ba1d648aeda973fae7bb981bafbb884165e514                 

Step 6: Report what is running in your environment #

First, run the artifact:

docker-compose up -d

Confirm the container is running:

docker ps

The output should include an entry similar to this:

CONTAINER ID  IMAGE      COMMAND                 CREATED         STATUS         PORTS                  NAMES
6330e545b532  nginx:1.21 "/docker-entrypoint.…"  35 seconds ago  Up 34 seconds  0.0.0.0:8080->80/tcp   quickstart-nginx

Report all the docker containers running on your machine to Kosli:

kosli snapshot docker quickstart

You can confirm this has created an environment snapshot:

kosli list snapshots quickstart
SNAPSHOT  FROM                           TO   DURATION
1         Tue, 01 Nov 2022 15:55:49 CET  now  11 seconds

You can get a detailed view of all the docker containers included in the snapshot report:

kosli get snapshot quickstart
COMMIT  ARTIFACT                                                                       FLOW  RUNNING_SINCE  REPLICAS
N/A     Name: nginx:1.21                                                               N/A   3 minutes ago  1
        Fingerprint: 8f05d73835934b8220e1abd2f157ea4e2260b9c26f6f63a8e3975e7affa46724

The kosli snapshot docker command reports all the docker containers running in your environment, equivalent to the output from docker ps. This tutorial only shows the nginx container in the examples.

If you refresh the Environments web page in your Kosli account, you will see that there is now a timestamp for Last Change At column. Select the quickstart link on left for a detailed view of what is currently running.

Step 7: Searching Kosli #

Now that you have reported your Artifact and what's running in your runtime environment, you can use the kosli search command to find everything Kosli knows about an Artifact or a git-commit.

For example, you can give Kosli search the git-commit whose CI run built and deployed the Artifact:

kosli search 9f14efa
Search result resolved to commit 9f14efa0c91807da9a8b1d1d6332c5b3aa24a310
