docs(*): update tiller_ssl.md to reflect IP SAN usage.
When using helm/tiller in tls-verify mode, 127.0.0.1 should
be listed as an IP SAN in the tiller certificate to pass
hostname verficiation of the TLS handshake.
Closes#4149
* fix(helm): add TLS params back
During a recent refactor, several TLS flags stopped being processed for
a few of the commands. This fixes those commands, and documents how to
set up TLS.
* fix(tiller): add stricter certificate verification
The older version of Tiller allowed a weaker set of certificate checks
than we intended. This version requires a client certificate, and then
requires that that certificate be signed by a known CA. This works
around the situation where a user could provide a self-signed
certificate.
It is now possible to create plugins with chart download capabilities for custom, non-http protocols.
Furthermore it is possible to reuse helm packages to implement alternative clients with these custom downloader functions.
This adds a hidden 'helm doc' command that generates documentation out
of the Helm help text.
Currently it can create:
- man pages for HELM(1)
- Markdown documentation
- bash autocompletions
Those are the three built-ins for Cobra.
The command is hidden so that it doesn't show up to the regular user,
since this is really a specialized task. It has the advantage of making
it trivially easy to install man pages and bash completion at installation time.
