Outdated cf cli version in tag "latest", compared to tag "v22"

[shinigami21]

Dear colleagues,

I am not sure why, but latest seems to be a step backwards (2025 -> 2020):

>docker run -it docker.wdf.sap.corp:50000/ppiper/cf-cli:latest sh
$ cf -v
cf version 6.53.0+8e2b70a4a.2020-10-01

>docker run -it docker.wdf.sap.corp:50000/ppiper/cf-cli:v22 sh
$ cf -v
cf version 8.14.1+2bcb856.2025-06-10

This is NOT an issue (not really) while using "cf login" as it is still using CF CLI v3. But while using "cf auth" it's falling back to CF CLI v2:

>docker run -it docker.wdf.sap.corp:50000/ppiper/cf-cli:latest sh
$ cf login -a https://api.cf.sap.hana.ondemand.com -u andreas.meier@sap.com -p abc --skip-ssl-validation
API endpoint: https://api.cf.sap.hana.ondemand.com

[...]

API endpoint:   https://api.cf.sap.hana.ondemand.com (API version: 3.203.0)

>docker run -it docker.wdf.sap.corp:50000/ppiper/cf-cli:latest sh
$ cf api api.cf.sap.hana.ondemand.com --skip-ssl-validation
Setting api endpoint to api.cf.sap.hana.ondemand.com...
OK

$ cf auth andreas.meier@sap.com abc
Cloud Foundry API version 2.268.0 requires CLI version 8.0.0. You are currently on version 6.53.0+8e2b70a4a.2020-10-01. To upgrade your CLI, please visit: https://github.com/cloudfoundry/cli#downloads

For testing "cf login" vs. "cf auth" please use a new docker instance! When you perform "cf login" in same instance first, "cf auth" will run on CF CLI v3 as well.

For my environment, I cannot use "cf login" as I need to build spaces etc. first (which are required for "cf login" but not for "cf auth").

Thx & BR,
Andreas
