This patch revises the SSL certificate management and
distribution with something that is more consistent with how
it's done everywhere else in the project. It also repairs the
current user provided certificate distribution which was broken.
* The server key/certificate (and optionally a CA cert) are
distributed to all horizon containers.
* Two new variables have been implemented for a user-provided
server key and certificate:
- horizon_user_ssl_cert: <path to cert on deployment host>
- horizon_user_ssl_key: <path to cert on deployment host>
If either of these is not defined, then the missing cert/key
will be self generated on the first Horizon container and
distributed to the other containers.
* A new variable has been implemented for a user-provided CA
certificate:
- horizon_user_ssl_ca_cert: <path to cert on deployment host>
* A new variable called 'horizon_ssl_self_signed_subject' has
been implemented to allow the user to override the self-signed
certificate properties, such as the CN and subjectAltName.
Upgrade notes:
* The Apache configuration appropriately implements the
'SSLCACertificateFile' instead of the 'SSLCACertificatePath'
directive in order to ensure that the appropriate signing
certificate is provided to the browser.
* The variable 'horizon_self_signed' (which defaulted to true)
has been removed. The decision of whether to generate a
self-signed certificate has been made based on whether a
user provided key/cert pair has been provided.
* The 'horizon_self_signed_regen' variable has been renamed
to 'horizon_ssl_self_signed_regen'.
* The default names for the deployed keys/certificates have been
changed:
- /etc/ssl/certs/apache.cert > /etc/ssl/certs/horizon.pem
- /etc/ssl/private/apache.key > /etc/ssl/private/horizon.key
