## Test notifications
|
|
|
|
Through the [command line](usage/cli.md) with:
|
|
|
|
```shell
|
|
$ diun --config ./diun.yml --test-notif
|
|
```
|
|
|
|
Or within a container:
|
|
|
|
```shell
|
|
$ docker-compose exec diun diun --test-notif
|
|
```
|
|
|
|
## field docker|swarm uses unsupported type: invalid
|
|
|
|
If you have the error `failed to decode configuration from file: field docker uses unsupported type: invalid` that's
|
|
because your `docker`, `swarm` or `kubernetes` provider is not initialized in your configuration:
|
|
|
|
!!! failure
|
|
```yaml
|
|
providers:
|
|
docker:
|
|
```
|
|
|
|
should be:
|
|
|
|
!!! success
|
|
```yaml
|
|
providers:
|
|
docker: {}
|
|
```
|
|
|
|
## No image found in manifest list for architecture, variant, OS
|
|
|
|
If you encounter this kind of warning, you are probably using the [file provider](providers/file.md) containing an
|
|
image with an erroneous or empty platform. If the platform is not filled in, it will be deduced automatically from the
|
|
information of your operating system on which Diun is running.
|
|
|
|
In the example below, Diun is running (`diun_x.x.x_windows_i386.zip`) on Windows 10 and tries to analyze the
|
|
`crazymax/cloudflared` image with the detected platform (`windows/386)`:
|
|
|
|
```yaml
|
|
- name: crazymax/cloudflared:2020.2.1
|
|
watch_repo: true
|
|
```
|
|
|
|
But this platform is not supported by this image as you can see [on DockerHub](https://hub.docker.com/layers/crazymax/cloudflared/2020.2.1/images/sha256-137eea4e84ec4c6cb5ceb2017b9788dcd7b04f135d756e1f37e3e6673c0dd9d2?context=explore):
|
|
|
|
!!! warning
|
|
`Fri, 27 Mar 2020 01:20:03 UTC WRN Cannot get remote manifest error="Cannot create image closer: Error choosing image instance: no image found in manifest list for architecture 386, variant \"\", OS windows" image=docker.io/image=crazymax/cloudflared:2020.2.1 provider=file`
|
|
|
|
You have to force the platform for this image if you are not on a supported platform:
|
|
|
|
```yaml
|
|
- name: crazymax/cloudflared:2020.2.1
|
|
watch_repo: true
|
|
platform:
|
|
os: linux
|
|
arch: amd64
|
|
```
|
|
|
|
!!! success
|
|
`Fri, 27 Mar 2020 01:24:33 UTC INF New image found image=docker.io/crazymax/cloudflared:2020.2.1 provider=file`
|
|
|
|
## Too many requests to registry
|
|
|
|
The error `Cannot create image closer: too many requests to registry` is returned when the HTTP status code returned
|
|
by the registry is 429.
|
|
|
|
This can happen on the DockerHub registry because of the [rate-limited anonymous pulls](https://docs.docker.com/docker-hub/download-rate-limit/).
|
|
|
|
To solve this you must first be authenticated against the registry through the [`regopts` settings](config/regopts.md):
|
|
|
|
```yaml
|
|
regopts:
|
|
- name: "docker.io"
|
|
selector: image
|
|
username: foo
|
|
password: bar
|
|
```
|
|
|
|
If this is not enough, tweak the [`schedule` setting](config/watch.md#schedule) with something
|
|
like `0 */6 * * *` (every 6 hours).
