Description of the change
This change allows users to specify company private URL for certificate URL which requires their proxy to fetch.
Benefits
In our company, since the certificate URL requires our proxy, we always use something like
kubeseal --cert <(curl -sSf "https://example.com/our-cert-file.cert")
(we sethttps_proxy
environment variable), or sometimeswget "https://example.com/our-cert-file.cert" && kubeseal --cert "our-cert-file.cert"
. It would be very useful if we can directly specify the private URL to--cert
.Possible drawbacks
I don't think there're any drawbacks.
