In a previous article (https://www.starkandwayne.com//blog/bosh-uaa-with-signed-certificates/) we discovered how to add a multiple/intermediate level signed certificates to UAA on BOSH. Recently I discovered one of my deployments had the certs in the wrong order and a kind gentleman named Thilak showed me how to verify the order of certificates is correct. While the
bosh_cli didn’t complain about the order other tools might so it’s good to get them in the right order. We should always strive to have nice things!
Start by running the
openssl and use the director url and port as seen below:
[email protected]:~$ openssl s_client -showcerts -connect bosh1.starkandwayne.com:25555
Now look at the output. In the example below there are 4 levels of certificates labeled 0 through 3. The certificate issued at a level should be signed from the previous level.
s: is the subject line of the certificate and
i: contains information about the issuing CA.
The ideal end result of a good openssl bingo:
Verify return code: 0 (ok)
