Configuration Options​
| Option | Details |
|---|---|
| skopeo_command | String. Defaults to skopeo. Command to be used to execute skopeo commands. May be overridden with another command that uses the same syntax, or a fully qualified path if skopeo is not on the default $PATH. |
| process_timeout | Number of seconds to attempt collect before timeout. Default: 300 |
Proxy and Certificate Configuration​
The Docker Collector plugin uses Skopeo to download container images, so the proxy and certificate configurations are not handled directly by the plugin, instead they must be configured as specified by Skopeo and its dependencies.
To configure proxies, set the following environment variables:
| Environment Variable Name | Description |
|---|---|
http_proxy | Proxy for the HTTP protocol. |
https_proxy | Proxy for the HTTPS protocol. |
no_proxy | Comma-separated list of domains where proxies won't be used. |
Skopeo uses the containers/image library, so for specifying certificates, a custom TLS configuration for a container registry can be configured by creating a directory under $HOME/.config/containers/certs.d or /etc/containers/certs.d. The name of the directory must correspond to the host:port of the registry (e.g., my-registry.com:5000). For more details, see [https://github.com/containers/image/blob/main/docs/containers-certs.d.5.md].
Credentials Configuration​
To specify credentials, you need a credentials file.
Sample credentials file:
---
schemaVersion: v1
kind: Credentials
metadata:
name: Registry Credentials
version: v1
description: Sample credentials file
credential_required_services:
- url: registry.gitlab.com
user_env: CI_REGISTRY_USER
pass_env: CI_REGISTRY_PASSWORD
