README
This Docker image is used for SAML authentication.
OpenShift Instructions
Secrets cannot have key names with an 'underscore' in them, so when creating a secret using a directory of files we need to rename the files accordingly.
Create the secret for the httpd saml configuration files (saml-sp.cert, saml-sp.key, saml-sp.xml, sp-idp-metadata.xml)
mkdir ./httpd-saml-config
cp saml-sp.cert saml-sp.key saml-sp.xml sp-idp-metadata.xml ./httpd-saml-config/
oc secrets new httpd-saml-config-secret ./httpd-saml-config
Create the secret for the httpd OSE certificates (authproxy.pem, ca.crt)
mkdir ./httpd-ose-certs
cp authproxy.pem ca.crt ./httpd-ose-certs/
oc secrets new httpd-ose-certs-secret ./httpd-ose-certs
Create the secret for the httpd server certificates (server.crt, server.key)
mkdir ./httpd-server-certs
cp server.crt server.key ./httpd-server-certs/
oc secrets new httpd-server-certs-secret ./httpd-server-certs
Create the docker image
docker build --tag=saml-auth .
docker tag -f <id> <repo>/saml-auth
docker push <repo>/saml-auth
Add saml-auth template to OSE - (required parameters: APPLICATION_DOMAIN, OSE_API_PUBLIC_URL)
oc create -f ./saml-auth.template -n openshift
Create a new application (test with '-o json', remove when satisfied with the result)
oc new-app saml-auth \
-p APPLICATION_DOMAIN=saml.example.com,OSE_API_PUBLIC_URL=https://ose.example.com:8443/oauth/authorize -o json
Add a secret for the SAML configuration (saml-sp.cert,saml-sp.key,saml-sp.xml,sp-idp-metadata.xml)
oc volume deploymentconfigs/saml-auth \
--add --overwrite --name=httpd-saml-config --mount-path=/etc/httpd/conf/saml \
--type=secret --secret-name=httpd-saml-config-secret
Add a secret for OSE certs (authproxy.pem,ca.crt)
oc volume deploymentconfigs/saml-auth \
--add --overwrite --name=httpd-ose-certs --mount-path=/etc/httpd/conf/ose_certs \
--type=secret --secret-name=httpd-ose-certs-secret
Add a secret for server certs (server.crt,server.key)
oc volume deploymentconfigs/saml-auth \
--add --overwrite --name=httpd-server-certs --mount-path=/etc/httpd/conf/server_certs \
--type=secret --secret-name=httpd-server-certs-secret
The template defines replicas as 0 so scale up:
oc scale --replicas=1 dc saml-auth
