Please read the following important pages that summarise technical requirements, systems and procedures within and around the Octanis Rover / Balloon project. Once you have a good overview, you can start working on one of the subsystems that we have categorised by “profession” on this page.

Before starting work

  • Join our Slack communication tool by asking info@octanis.org
  • Read Technical requirements for Mechanical & Electrical Systems and Flight Software
  • Read Schema of Rover Systems and Interfaces
  • Check the issues list for open issues and pick the issue you want to work on.

Today we are releasing the Slack orb v4.0 for CircleCI. It makes pipeline notifications easy to implement and customize. Now with support for Slack’s Block Kit Builder, it also provides a visual way to create endless custom notifications. Check out the slack orb here:

What’s new?

Simple to use.

Previously, the Slack orb utilized multiple commands and numerous orb parameters to build notifications piece-by-piece. Now, with version 4.0 and above, you can select one of several built-in available templates or customize and import your own notifications visually with Slack’s Block Kit Builder.

In the new Slack orb you will only find a single command notify, and a job on-hold. The notify command is the heart of the orb and can be used to send notifications to any (or multiple) Slack channel based on events like when a CircleCI job has passed or failed.

Built for teams

The new Slack orb authenticates using OAuth, rather than using incoming webhooks as in previous versions. With this change, you can now install a “bot” application in your Slack Workspace for your CircleCI notifications and alert multiple channels from one integration. To setup authentication, be sure to check the GitHub wiki for the Slack orb

Upgrading

Slack orb version 4.0.0 is a complete rewrite of the previous Slack orb with a new feature set and simpler design that is much easier to use. Older versions of the Slack orb will continue to operate and migrating to the new Slack orb experience is entirely optional.

To migrate to the new Slack orb, the old orb must be completely removed as version 4.0 does not share any functionality with previous versions of the orb.

Get started by visiting the GitHub wiki

How does it work?

Saints row 4 mac free download. Orbs are packages of CircleCI configuration which can be imported and utilized in your configuration file.

To jump ahead, you can view the Slack orb in the orb registry, and on GitHub.

The main component of the Slack orb is the notify command, which can be used at the end of any job to send notifications based on the status of that job.

There is now a single notification command with an event parameter. The notify command should be placed at the end of any job as it will always run and can detect the current status of the job.

You can specify notifications to always send or to send on fail or pass. If a branch_pattern parameter is specified, the current branch must also match the pattern to send the notification.

For the message body, you can select one of the preconfigured templates included with the orb, or create your own custom notification.

You can see a full list of available templates on the GitHub Wiki.

By default, the Slack orb will attempt to post to the channel specified by the $SLACK_DEFAULT_CHANNEL environment variable, but you can also select one or more channels via the channel parameter.

A working example

Here is a semi-realistic example of a test and deploy workflow on CircleCI. It has one job which tests the application on every commit (test), and a deployment job which only runs on a tagged commit (deploy).

In this example, we will place our workflow (test-and-deploy) On hold prior to deployment, and wait for a manual approval. After an engineer manually approves the workflow, the deployment job will execute. For this workflow, we want to set up three potential notifications for Slack:

  • A notification when the workflow is placed on-hold
  • A notification if the deployment fails
  • A different notification if the deployment succeeds

The following usage example is pulled directly from the orb registry. Express zip registration code.

This configuration makes two assumptions:

  1. You have stored your OAuth token as $SLACK_ACCESS_TOKEN in a restricted context named slack-secrets
  2. You have defined the $SLACK_DEFAULT_CHANNEL as either a project environment variable, or within the slack-secrets context.

Creating custom notifications

Previously, creating custom notifications involved using many parameters. They were limited and difficult to configure. Now, you can create nearly any notification imaginable with only a single parameter, and notifications are designed visually using Slack’s Block Kit Builder.You can start with any of Slack’s built-in templates, or start fresh and design your own.

On the right side of the screen above, you get the payload that contains the text we feed to the Slack orb via the custom parameter (as an alternative to the template parameter).
