Querying Kosli

This tutorial shows you how to use Kosli’s query commands to search for artifacts, inspect their history, and browse runtime environment snapshots.

get, list, log, and diff commands let you query everything Kosli knows about your artifacts and environments directly from your terminal. By the end of this tutorial, you will have searched for an artifact by commit SHA, inspected its full history, browsed environment snapshots, and compared two snapshots to see what changed.

We will query cyber-dojo, an open-source project whose Kosli data is public.

Prerequisites

• Install Kosli CLI.
• Get a Kosli API token.

Setup

export KOSLI_ORG=cyber-dojo
export KOSLI_API_TOKEN=<your-api-token>

Search by commit SHA

If you have a git commit SHA, kosli search will find any artifact built from it:

kosli search 0f5c9e1

List flows and artifacts

The search result tells us this artifact belongs to the web flow. If you don’t know which flows exist in your org, you can list them all:

kosli list flows

Once you know the flow name, you can list the artifacts reported to it:

kosli list artifacts --flow creator

By default, the last 15 artifacts are shown. Use -n to change how many are shown, —page to paginate, and —output to change the format.

Get an artifact

The artifact list gives you commit SHAs and fingerprints. Use either to fetch the full history of a specific artifact — the syntax is flow:sha or flow@fingerprint:

kosli get artifact creator:344430d

Browse environment snapshots

The artifact history shows it was deployed to aws-beta and aws-prod. To explore those environments, start by listing what Kosli knows about them:

kosli list environments

NAME      TYPE  LAST REPORT                LAST MODIFIED
aws-beta  ECS   2022-10-30T14:51:42+01:00  2022-10-30T14:51:42+01:00
aws-prod  ECS   2022-10-30T14:51:28+01:00  2022-10-30T14:51:28+01:00
beta      K8S   2022-06-15T11:39:59+02:00  2022-06-15T11:39:59+02:00

To browse the history of changes in an environment:

kosli list snapshots aws-beta

...

To see what was running in a specific snapshot:

kosli get snapshot aws-beta#256

[...]

You can also reference snapshots relatively — aws-beta~1 means one behind the current snapshot, aws-beta~19 means 19 behind.

Compare snapshots

Now that you can see individual snapshots, you can also diff two of them to find out exactly what changed between any two points in time:

kosli diff snapshots aws-beta aws-beta~1

Only present in aws-beta (snapshot: aws-beta#266)

     Name:         244531986313.dkr.ecr.eu-central-1.amazonaws.com/dashboard:d90a3e4

     Started:      Wed, 19 Oct 2022 09:47:33 CEST • 11 days ago

You can also diff two different environments to see what’s running in one but not the other:

kosli diff snapshots aws-beta~3 aws-prod

What you’ve accomplished

You have searched for an artifact by commit SHA, inspected a flow’s artifact list, fetched an artifact’s full history, browsed environment snapshots, and diffed two snapshots to see exactly what changed.

From here you can:

• Learn more about kosli search, kosli get artifact, and kosli diff snapshots in the CLI reference
• See a real end-to-end example in the From commit to production tutorial
