The ATC is statically configured with a Credhub server URL with TLS and client config.
For example, to point the ATC at an internal Credhub server with TLS signed by a local CA, using client id and secret, you may configure:
concourse web ... \ --credhub-url https://10.2.0.3:9000 \ --credhub-ca-cert /etc/my-ca.cert \ --credhub-client-id =db02de05-fa39-4855-059b-67221c5c2f63 \ --credhub-client-secret 6a174c20-f6de-a53c-74d2-6018fcceff64
When resolving a parameter such as
((foo_param)), it will look in the following paths, in order:
/concourse can be changed by specifying
Credhub credentials actually have different types, which may contain multiple values. For example, the
user type specifies both
password. You can specified the field to grab via
. syntax, e.g.
If the action is being run in the context of a pipeline (e.g. a
check or a step in a build of a job), the ATC will first look in the pipeline path. If it's not found there, it will look in the team path. This allows credentials to be scoped widely if they're common across many pipelines.
If an action is being run in a one-off build, the ATC will only look in the team path.
