For up to date versions of wrangler, secrets are uploaded via the
'secret:bulk' command, which batches updates in a single API call.
For versions of wrangler without that capability, the action falls back
to the single 'secret put' command for each secret. It races all these
with a Promise.all()
Unfortunately, the single secret API cannot handle concurrency - at
best, these calls have to wait on one another, holding requests open
all the while. Often it times out and errors.
This fixes the legacy secret upload errors by making these calls
serially instead of concurrently.
Currently our release process is kicked off whenever a PR is merged and there are no changesets within the `.changeset` directory. Typically this happens when we intend to publish a release, just after we merge a "Version Packages" PR which removes the changesets and adds the entries to our changelog.
However, this also means that merging any PR without user-facing changes during the period after we've made a release will trigger another release (which luckily fails because the created tag already exists on the remote. See #184).
This change avoids that scenario by fetching tags when checking out the repo. Now when `npx changeset tag` runs, it will see that the tag already exists and skip creating it (`🦋 Skipping tag (already exists): v3.3.2`). The `git push --tags` step will no longer throw an error ("Everything up-to-date"). And lastly, the publish step won't get triggered because the output from `npx changeset tag` doesn't contain the string `"New tag:"`. The action should just finish successfully with nothing to left do.
Fixes#184
If the token isn't specified, wrangler throws this error, indicating the CLOUDFLARE_API_TOKEN should be set, so it's worth being consistent so folks can copy/paste the examples and have it work out of the box:
```
In a non-interactive environment, it's necessary to set a CLOUDFLARE_API_TOKEN environment variable for wrangler to work.
```
Instead of using a mix of `child_process.exec`, `child_process.execSync` and a promisified version of `child_process.exec`, we now (mostly) just use `@actions/exec`. That runs `child_process.spawn` under the hood and handles a lot of character escaping for us. We can also now pass Buffers directly into the subprocess as stdin instead of relying on shell piping.
This ends up fixing a few problems we had where secrets and env var values containing shell metacharacters were being misinterpreted.
Unfortunately, `@actions/exec` doesn't support running with a shell. That means we still have to roll our own wrapper around `child_process.exec` to avoid a breaking change to `preCommands` and `postCommands`, since users might be expecting these to run within a shell.
Also worth noting that we're no longer hiding stdout and stderr from the secret uploading step. We were previously doing this out of an abundance of caution, but it made debugging issues very difficult if secret upload failed for some reason. I feel ok doing this since we're no longer echoing & piping the secret values, wrangler doesn't ever output secret values, and as a last line of defense GitHub masks any secret values that accidentally get logged.
We need to distinguish between when the value is and isn't set in order to perform inference based on lockfile and only fallback to the default of npm if inference fails.
Some of the stderr, stdout, info & groupings can be a little noisy for some users and use cases.
This feature allows for a option to be passed 'quiet: true' this would significantly reduce the noise.
There will still be output that lets the user know Wrangler Installed and Wrangler Action completed successfully.
Any failure status will still be output to the user as well, to prevent silent failures.
resolves#142
- [#147](https://github.com/cloudflare/wrangler-action/pull/147) [`58f274b`](https://github.com/cloudflare/wrangler-action/commit/58f274b9f70867447519c6fa983c813e2b167b85) Thanks [@JacobMGEvans](https://github.com/JacobMGEvans)! - Added more error logging when a command fails to execute
Previously, we prevented any error logs from propagating too far to prevent leaking of any potentially sensitive information. However, this made it difficult for developers to debug their code.
In this release, we have updated our error handling to allow for more error messaging from pre/post and custom commands. We still discourage the use of these commands for secrets or other sensitive information, but we believe this change will make it easier for developers to debug their code.
Easy-to-use GitHub Action to use [Wrangler](https://developers.cloudflare.com/workers/cli-wrangler/). Makes deploying Workers, Pages or modifying R2 easy to do.
## Big Changes in v3
- Wrangler v1 is no longer supported.
- Global API key & Email Auth no longer supported
- Action version syntax is newly supported. This means e.g. `uses: cloudflare/wrangler-action@v3` and `uses: cloudflare/wrangler-action@v3.x` are both now valid syntax. Previously supported syntax e.g. `uses: cloudflare/wrangler-action@3.x.x` continues to be supported.
[Refer to Changelog for more information](CHANGELOG.md).
## Usage
Add `wrangler-action` to the workflow for your Workers/Pages application. The below example will deploy a Worker on a `git push` to the `main` branch:
```yaml
name:Deploy
on:
push:
branches:
- main
jobs:
deploy:
runs-on:ubuntu-latest
name:Deploy
steps:
- uses:actions/checkout@v3
- name:Deploy
uses:cloudflare/wrangler-action@3.0.0
with:
apiToken:${{ secrets.CF_API_TOKEN }}
```
## Authentication
You'll need to configure Wrangler using GitHub's Secrets feature - go to "Settings -> Secrets" and add your Cloudflare API token (for help finding this, see the [Workers documentation](https://developers.cloudflare.com/workers/quickstart/#api-token)). Your API token is encrypted by GitHub, and the action won't print it into logs, so it should be safe!
With your API token set as a secret for your repository, pass it to the action in the `with` block of your workflow. Below, I've set the secret name to `CF_API_TOKEN`:
```yaml
jobs:
deploy:
name:Deploy
steps:
uses:cloudflare/wrangler-action@3.0.0
with:
apiToken:${{ secrets.CF_API_TOKEN }}
```
## Configuration
If you need to install a specific version of Wrangler to use for deployment, you can also pass the input `wranglerVersion` to install a specific version of Wrangler from NPM. This should be a [SemVer](https://semver.org/)-style version number, such as `2.20.0`:
```yaml
jobs:
deploy:
steps:
uses:cloudflare/wrangler-action@3.0.0
with:
apiToken:${{ secrets.CF_API_TOKEN }}
wranglerVersion:"2.20.0"
```
Optionally, you can also pass a `workingDirectory` key to the action. This will allow you to specify a subdirectory of the repo to run the Wrangler command from.
```yaml
jobs:
deploy:
steps:
uses:cloudflare/wrangler-action@3.0.0
with:
apiToken:${{ secrets.CF_API_TOKEN }}
workingDirectory:"subfoldername"
```
[Worker secrets](https://developers.cloudflare.com/workers/tooling/wrangler/secrets/) can optionally be passed in via `secrets` as a string of names separated by newlines. Each secret name must match the name of an environment variable specified in the `env` field. This creates or replaces the value for the Worker secret using the `wrangler secret put` command.
```yaml
jobs:
deploy:
steps:
uses:cloudflare/wrangler-action@3.0.0
with:
apiToken:${{ secrets.CF_API_TOKEN }}
secrets:|
SECRET1
SECRET2
env:
SECRET1:${{ secrets.SECRET1 }}
SECRET2:${{ secrets.SECRET2 }}
```
If you need to run additional shell commands before or after your command, you can specify them as input to `preCommands` (before `deploy`) or `postCommands` (after `deploy`). These can include additional `wrangler` commands (that is, `whoami`, `kv:key put`) or any other commands available inside the `wrangler-action` context.
```yaml
jobs:
deploy:
steps:
uses:cloudflare/wrangler-action@3.0.0
with:
apiToken:${{ secrets.CF_API_TOKEN }}
preCommands:echo "*** pre command ***"
postCommands:|
echo "*** post commands ***"
wrangler kv:key put --binding=MY_KV key2 value2
echo "******"
```
You can use the `command` option to do specific actions such as running `wrangler whoami` against your project:
```yaml
jobs:
deploy:
steps:
uses:cloudflare/wrangler-action@3.0.0
with:
apiToken:${{ secrets.CF_API_TOKEN }}
command:whoami
```
## Use cases
### Deploy when commits are merged to main
The above workflow examples have already shown how to run `wrangler-action` when new commits are merged to the main branch. For most developers, this workflow will easily replace manual deploys and be a great first integration step with `wrangler-action`:
```yaml
on:
push:
branches:
- main
jobs:
deploy:
runs-on:ubuntu-latest
name:Deploy
steps:
- uses:actions/checkout@v3
- name:Deploy
uses:cloudflare/wrangler-action@3.0.0
with:
apiToken:${{ secrets.CF_API_TOKEN }}
```
Note that there are a number of possible events, like `push`, that can be used to trigger a workflow. For more details on the events available, refer to the [GitHub Actions documentation](https://help.github.com/en/articles/workflow-syntax-for-github-actions#on).
### Deploy your Pages site (production & preview)
If you want to deploy your Pages project with GitHub Actions rather than the built-in continous integration (CI), then this is a great way to do it. Wrangler 2 will populate the commit message and branch for you. You only need to pass the project name. If a push to a non-production branch is done, it will deploy as a preview deployment:
```yaml
on:[push]
jobs:
deploy:
runs-on:ubuntu-latest
name:Deploy
steps:
- uses:actions/checkout@v3
- name:Deploy
uses:cloudflare/wrangler-action@3.0.0
with:
apiToken:${{ secrets.CF_API_TOKEN }}
accountId:${{ secrets.CF_ACCOUNT_ID }}
command:pages deploy --project-name=example
```
### Deploying on a schedule
If you would like to deploy your Workers application on a recurring basis – for example, every hour, or daily – the `schedule` trigger allows you to use cron syntax to define a workflow schedule. The below example will deploy at the beginning of every hour:
```yaml
on:
schedule:
- cron:"0 * * * *"
jobs:
deploy:
runs-on:ubuntu-latest
name:Deploy
steps:
- uses:actions/checkout@v3
- name:Deploy app
uses:cloudflare/wrangler-action@3.0.0
with:
apiToken:${{ secrets.CF_API_TOKEN }}
```
If you need help defining the correct cron syntax, check out [crontab.guru](https://crontab.guru/), which provides a friendly user interface for validating your cron schedule.
### Manually triggering a deployment
If you need to trigger a workflow at-will, you can use GitHub's `workflow_dispatch` [event](https://docs.github.com/en/actions/reference/events-that-trigger-workflows#workflow_dispatch) in your workflow file. By setting your workflow to trigger on that event, you will be able to deploy your application via the GitHub UI. The UI also accepts inputs that can be used to configure the action:
```yaml
on:
workflow_dispatch:
inputs:
environment:
description:"Choose an environment to deploy to: <dev|staging|prod>"
For more advanced usage or to programmatically trigger the workflow from scripts, refer to [the GitHub documentation](https://docs.github.com/en/rest/reference/actions#create-a-workflow-dispatch-event) for making API calls.
## Troubleshooting
### "I just started using Workers/Wrangler and I don't know what this is!"
Refer to the [Quick Start guide](https://developers.cloudflare.com/workers/quickstart) to get started. Once you have a Workers application, you may want to set it up to automatically deploy from GitHub whenever you change your project.
### "[ERROR] No account id found, quitting.."
You will need to add `account_id = ""` in your `wrangler.toml` file or set `accountId` in this GitHub Action.
