viya-single-container running on K8S cluster cannot apply a new SAS license without rebuild about sas-container-recipes

[splmie]

I found the solution by myself.

1. Create kubernetes config map with spre.SETINIT_TEXT variable
2. Put the content of your new SAS license into spre.SETINIT_TEXT.

  spre.SETINIT_TEXT: |
    PROC SETINIT RELEASE='V03';
    SITEINFO NAME='XXXXXXXX'
    SITE=123456789 OSNAME='LIN X64' RECREATE WARN=34 GRACE=62
    [..]
    SAVE; RUN;

3. Inside the SPRE container set environment variable SETINIT_TEXT and initialize it with value of spre.SETINIT_TEXT from kubernetes config map.

TIP: you have to modify the manifest starting your SPRE container by putting this section

    spec:
      containers:
      - env:
        - name: SETINIT_TEXT
          valueFrom:
            configMapKeyRef:
              key: spre.SETINIT_TEXT
              name: spre-config

4. entrypoint for the SPRE image need to be modified by putting that code before CAS starts

   echo;echo "===== [INFO] : Checking SAS license =====";

      if [ ! -z "${SETINIT_TEXT}" ]; then
          export SASLICENSEFILE="license.sas"
          export SASLICENSEDIR="/sasinside"
          echo;echo "===== [INFO] : Found new SAS license! =====";echo;
          echo;echo "${SETINIT_TEXT}";echo;
          echo;echo "===== [INFO] : Applying new SAS license =====";echo;
          echo "${SETINIT_TEXT}" > ${SASLICENSEDIR}/${SASLICENSEFILE}
          # Applying license to SAS Foundation
          sudo su -s "/bin/sh" -c "/opt/sas/spre/home/SASFoundation/utilities/bin/apply_license ${SASLICENSEDIR}/${SASLICENSEFILE}" sas
          # Applying license to CAS
          sudo su -s "/bin/sh" -c "ln -sf ${SASLICENSEDIR}/${SASLICENSEFILE} /opt/sas/viya/config/etc/cas/default/sas_license.txt" sas
      else
          echo;echo "===== [INFO] : No changes, skipping  =====";echo;
      fi
