## Cannot push to a registry
|
|
|
|
While pushing to a registry, you may encounter these kinds of issues:
|
|
|
|
* `failed commit on ref "layer-sha256:...": invalid content digest in response: invalid checksum digest format`
|
|
* `failed commit on ref "layer-sha256:...": no response`
|
|
* `failed commit on ref "manifest-sha256:...": unexpected status: 400 Bad Request`
|
|
* `failed commit on ref "manifest-sha256:...": unexpected status: 401 Unauthorized`
|
|
* `unexpected response: 401 Unauthorized`
|
|
|
|
These issues are not directly related to this action but are rather linked to [buildx](https://github.com/docker/buildx),
|
|
[buildkit](https://github.com/moby/buildkit), [containerd](https://github.com/containerd/containerd) or the registry
|
|
on which you're pushing your image. The quality of error message depends on the registry and are usually not very informative.
|
|
|
|
To help you solve this, you should first enable debugging in the
|
|
[setup-buildx action step](https://github.com/docker/setup-buildx-action):
|
|
|
|
```yaml
|
|
-
|
|
name: Set up Docker Buildx
|
|
uses: docker/setup-buildx-action@v1
|
|
with:
|
|
buildkitd-flags: --debug
|
|
```
|
|
|
|
Next you can test pushing with [containerd action](https://github.com/crazy-max/ghaction-setup-containerd) using the
|
|
following workflow. If it works then open an issue on [buildkit](https://github.com/moby/buildkit) repository.
|
|
|
|
```yaml
|
|
name: containerd
|
|
|
|
on:
|
|
push:
|
|
|
|
jobs:
|
|
containerd:
|
|

|
|
