I am using a multiple puppet master setup with puppet dashboard running on a separate server. I have also configured dashboard to use https running with passenger. I would like to turn puppet dashboard in to an ENC.
I have set the following configuration on each puppet master (excuse the spaces in the link):
node_terminus = exec external_nodes = /usr/bin/env PUPPET_DASHBOARD_URL=https:// puppet-dashboard /usr/share/puppet-dashboard/bin/external_node
I have edited the external_node ruby script and specified the https URL for the dashboard, however I am getting this error on the puppet nodes:
Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Failed when searching for node ukserver0028.domain.net: Failed to find ukserver0028.domain.net via exec: Execution of '/usr/bin/env PUPPET_DASHBOARD_URL=https://puppet-dashboard /usr/share/puppet-dashboard/bin/external_node ukserver0028.domain.net' returned 127: Error: Could not retrieve catalog; skipping run
selinux is set to permissive
I have run the following command on the puppet master
/usr/bin/env PUPPET_DASHBOARD_URL=https://puppet-dashboard /usr/share/puppet-dashboard/bin/external_node ukserver0028.domain.net
but I get this error:
/usr/lib/ruby/1.8/net/http.rb:586:in `connect': SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (OpenSSL::SSL::SSLError)
This pointed me to the external_node script and the path to the SSL certs
CERT_PATH PKEY_PATH CA_PATH
I edited the external_node file and pointed to the certs that are used by dashboard SSL, which were created by the rake tool.
$ sudo -u puppet-dashboard rake cert:create_key_pair $ sudo -u puppet-dashboard rake cert:request
I also noted that the common name is actually dashboard, not puppet-dashboard which is my c-name in DNS. I can now run the following command successfully.
/usr/bin/env PUPPET_DASHBOARD_URL=https://dashboard /usr/share/puppet-dashboard/bin/external_node puppet.domain.net
However, if I run the same command using any other node than the puppet master or puppet-dashboard server, I get an SSL error, I suppose as the other puppet nodes in the environment are not aware or the puppet certs created by the rake tool to enable HTTPS on dashboard.
Therefore, what are the certs I should be using in the external_node file?
Further to this, I have a sandpit environment with puppet-dashboard that runs just using http. I have the set up working by specifying the path to the external_node set correctly in puppet.conf and configuring the external_node file to use HTTP. So there is definitely something amiss when using dashboard running on HTTPS.
Many thanks - Oli
