Docker images of a simple nginx server and a client to allow full verification of an ssl certificate to a root ca certificate.
-
For the server, add:
- the ssl certificate as
server/config/ssl/cert.pem - the ssl certificate's key as
server/config/ssl/cert.key.pem
- the ssl certificate as
-
For the client, add:
- the root ca certificate to
client/config/ssl/
- the root ca certificate to
-
In an editor, open the
docker-compose.ymlfile, then 'find and replace' the stringREPLACE-ME-WITH-FQDNwith the ssl certificate'sfully.qualified.domain.name, e.g. replaceREPLACE-ME-WITH-FQDNwithwww.amazon.com(if you happen to be testing the Amazon ssl certificate!)
Note: If changes are made to the certificate files on either the client or the server, simply teardown the stack and relaunch (see instruction below).
The following examples show testing an ssl certificate for the domain pki.my-test-domain.com
-
Launch
$ docker-compose up [--build] # then, watch the logsThe
--buildswitch is of course optional, should you need to rebuild the docker images at any point in the future. -
Test
In another shell...

Alternatively, to debug or test from the client box...
# jump on the client box $ docker exec -it ssl-cert-test-client bash # then issue commands from there, e.g. $ curl -v https://pki.my-test-domain.com/ # or even $ ping pki.my-test-domain.com
-
Teardown
# if on the client box, first... bash-4.4# exit $ docker-compose down
