letsencrypt support This change contains the roles and testing for deploying certificates on hosts using letsencrypt with domain authentication. From a top level, the process is implemented in the roles as follows: 1) letsencrypt-acme-sh-install This role installs the acme.sh tool on hosts in the letsencrypt group, along with a small custom driver script to help parse output that is used by later roles. 2) letsencrypt-request-certs This role runs on each host, and reads a host variable describing the certificates required. It uses the acme.sh tool (via the driver) to request the certificates from letsencrypt. It populates a global Ansible variable with the authentication TXT records required. If the certificate exists on the host and is not within the renewal period, it should do nothing. 3) letsencrypt-install-txt-record This role runs on the adns server. It installs the TXT records generated in step 2 to the acme.opendev.org domain and then refreshes the server. Hosts wanting certificates will have pre-provisioned CNAME records for _acme-challenge.host.opendev.org pointing to acme.opendev.org. 4) letsencrypt-create-certs This role runs on each host, reading the same variable as in step 2. However this time the acme.sh tool is run to authenticate and create the certificates, which should now work correctly via the TXT records from step 3. After this, the host will have the full certificate material. Testing is added via testinfra. For testing purposes requests are made to the staging letsencrypt servers and a self-signed certificate is provisioned in step 4 (as the authentication is not available during CI). We test that the DNS TXT records are created locally on the CI adns server, however. Related-Spec: https://review.openstack.org/587283 Change-Id: I1f66da614751a29cc565b37cdc9ff34d70fdfd3f

Generate ssl check list directly from letsencrypt variables This autogenerates the list of ssl domains for the ssl-cert-check tool directly from the letsencrypt list. The first step is the install-certcheck role that replaces the puppet-ssl_cert_check module that does the same. The reason for this is so that during gate testing we can test this on the test bridge.openstack.org server, and avoid adding another node as a requirement for this test. letsencrypt-request-certs is updated to set a fact letsencrypt_certcheck_domains for each host that is generating a certificate. As described in the comments, this defaults to the first host specified for the certificate and the listening port can be indicated (if set, this new port value is stripped when generating certs as is not necessary for certificate generation). The new letsencrypt-config-certcheck role runs and iterates all letsencrypt hosts to build the final list of domains that should be checked. This is then extended with the letsencrypt_certcheck_additional_domains value that covers any hosts using certificates not provisioned by letsencrypt using this mechanism. These additional domains are pre-populated from the openstack.org domains in the extant check file, minus those openstack.org domain certificates we are generating via letsencrypt (see letsencrypt-create-certs/handlers/main.yaml). Additionally, we update some of the certificate variables in host_vars that are listening on port !443. As mentioned, bridge.openstack.org is placed in the new certcheck group for gate testing, so the tool and config file will be deployed to it. For production, cacti is added to the group, which is where the tool currently runs. The extant puppet installation is disabled, pending removal in a follow-on change.

letsencrypt: split staging and self-signed generation We currently only have letsencrypt_test_only as a single flag that sets tests to use the letsencrypt staging environment and also generates a self-signed certificate. However, for initial testing we actually want to fully generate certificates on hosts, but using the staging environment (i.e. *not* generate self-signed certs). Thus we need to split this option into two, so the gate tests still use staging+self-signed, but in-progress production hosts can just using the staging flag. These variables are split, and graphite01.opendev.org is made to create staging certificates. Also remove some debugging that is no longer necessary.

Use handlers for letsencrypt cert updates This change proposes calling a handler each time a certificate is created/updated. The handler name is based on the name of the certificate given in the letsencrypt_certs variable, as described in the role documentation. Because Ansible considers calling a handler with no listeners an error this means each letsencrypt user will need to provide a handler. One simple option illustrated here is just to produce a stamp file. This can facilitate cross-playbook and even cross-orchestration-tool communication. For example, puppet or other ansible playbooks can detect this stamp file and schedule their reloads, etc. then remove the stamp file. It is conceivable more complex listeners could be setup via other roles, etc. should the need arise. A test is added to make sure the stamp file is created for the letsencrypt test hosts, which are always generating a new certificate in the gate test.
