# crane
A GitLab CI ready image to upgrade services in Rancher.

## Usage
1. Deploy your application on Rancher manually,
with an image tagged with a git reference
(our recommendation is to use the commit SHA, but you can also use git tags.)
2. Get a Rancher Environment API key
and add the API keypair as secret variables in the project,
named `RANCHER_ACCESS_KEY` and `RANCHER_SECRET_KEY`.
3. Also add `RANCHER_URL` and `RANCHER_ENV_ID`,
preferably in secret variables, or in `.gitlab-ci.yml`.
(In the example URL `https://rancher.example.com/env/1a81/apps/stacks/1e551/services/1s1456/containers`
the environment ID is `1a81`. This ID always starts with `1a`.)
4. Add something like this to your `.gitlab-ci.yml`:
```yaml
stages:
# [...]
- deploy
deploy-production:
stage: deploy
image: kiwicom/crane:3.2.1
script:
- crane --stack my-app --service api --service worker
environment:
name: production
url: https://my-app.example.com/
when: manual
```

## Integrations & Extensions
### Slack
When `--slack-token` is set,
crane can post an announcement to `--slack-channel`
with details about the ongoing deployment.
You can use `--slack-link` to add useful URLs to this announcements
such as Datadog dashboards, Sentry issues, or the project repository.
You can set `--slack-channel` multiple times;
all channels will have the same annnouncement posted to them.
If you're setting the channel names via the environment variable,
separate them with a space.
| CLI flag | Environment variable | Details |
| ----------------- | --------------------- | ----------------------------- |
| `--slack-token` | `CRANE_SLACK_TOKEN` | Slack API token |
| `--slack-channel` | `CRANE_SLACK_CHANNEL` | Slack channels to announce in |
| `--slack-link` | `CRANE_SLACK_LINK` | links to mention in Slack |
### Sentry
With `--sentry-webhook`, crane can post release details to Sentry.
[Release tracking](https://docs.sentry.io/learn/releases/#what-is-a-release) is useful
to provide additional context to errors tracked in Sentry.
| CLI flag | Environment variable | Details |
| ------------------ | ---------------------- | -------------------------- |
| `--sentry-webhook` | `CRANE_SENTRY_WEBHOOK` | Sentry release webhook URL |
### Datadog
If you set an API key with `--datadog-key`,
Crane will post successful and failed releases to your Datadog event feed.
These events can then be marked on charts and displayed on dashboards.
| CLI flag | Environment variable | Details |
| --------------- | -------------------- | ---------------------------- |
| `--datadog-key` | `CRANE_DATADOG_KEY` | URLs to post release info to |
### Generic webhooks
With the `--webhook-url` option,
you can specify URLs that crane will send release info to,
in its own format.
One use for this is for analytics;
if somebody sets up a listener for these events,
they'll have the data needed to identify correlations
between releases and changes in user behavior or sales numbers.
| CLI flag | Environment variable | Details |
| ----------------- | --------------------- | ---------------------------- |
| `--webhook-url` | `CRANE_WEBHOOK_URL` | URLs to post release info to |
| `--webhook-token` | `CRANE_WEBHOOK_TOKEN` | Auth token for webhooks |
