Help to get started Docker Tools/CAS

Also, I precise that I think the team abandonned this GitHub project for https://github.com/apereo/cas which have a docker folder, but there is not possible to submit issues... and I think this GitHub project is about version 5.0.x because there is no commit since 2 years...

Hi,

Did you solve your problem ?

For your first question, I think there is no build.sh and run.sh. But, in /cas-overlay/bin, there is run-cas.sh to start CAS. If you want rebuild CAS, I don't know how, but I'm interrested. I want use LDAP authentication but it doesn't work, so I think I must rebuild the app... The documentation is not very clear about Docker version...

For your second question, I'm not sure I understand, but try to use 8080 port.

My problem still is that CAS image fails to successfully start on my local container with few warnings and the error (see log fragment below), and I'm trying to figure out if that's because missing/not configured keystore or issue with Tomcat configuration.

I've tried same on Dock for Mac with the identical failure. So, I'm sure I'm missing some simple step here and positive someone else had similar experience.

Com'on folks, someone give us a hint!

CAS is configured to accept a static list of credentials for authentication. While this is generally useful for demo purposes, it is STRONGLY recommended that you DISABLE this authentication method (by setting 'cas.authn.accept.users' to a blank value) and switch to a mode that is more suitable for production.>

To configure my keystore, I've created my own Dockerfile who inherits from apereo/cas:v5.3.2.

In this Dockerfile, I do some things like configure my proxy, install Kerberos and configure CAS (it was working with v5.0.6, but not with the v5.3.2).

To generate my keystore, I use these 2 command lines because I need to modify $JAVA_HOME/lib/security/cacerts and before I had to create /etc/cas/thekeystore. I don't know if /etc/cas/thekeystore is still needed :

RUN keytool -genkey -keyalg RSA -alias cas -keystore /etc/cas/thekeystore -storepass changeit -validity 9999 -keysize 2048 -dname "cn=cas.local, ou=MyOU, o=MyCompany, c=FR, st=Nord, l=MyCity" && \
    keytool -genkey -keyalg RSA -alias cas -keystore $JAVA_HOME/lib/security/cacerts -storepass changeit -validity 9999 -keysize 2048 -dname "cn=cas.local, ou=MyOU, o=MyCompany, c=FR, st=Nord, l=MyCity"

Thanks for the tip. I will try that and let you know if that makes difference.
