1. Run git add global/overlay/etc/hiera/data/common.yaml and git commit. You should ofcourse have right to commit in the repository.
2. Run the script thiss-ops/bump-tag afterwards.
3. To verify that the new version is installed, log in to the servers static-1.thiss.io and static-2.thiss.io and enter 'run-cosmo -v'. 
4. You can check the status by running the command service docker-thiss_js status.
5. You can also enter 'docker ps' in order to see if the new version is present on docker image tag.
6. We may have to do more than one version upgrade to make it backward compatible, check https://github.com/TheIdentitySelector/thiss-js/blob/staging/RELEASE.md
7. Check that the login works using demo.beta.seamlessaccess.org. You can check the transaction check & page speed in Pingdom after each upgrade. Page speed shows the response headers and other information for each file loaded from https://use.thiss.io.
8. It is also good to check the HIT ratio (observability > service overview) and origin latency under CDN services from Fastly GUI for the service 'use.thiss.io'. Chek that the HIT ratio is high enough, should be around 98 to 99 percent, latency is way below 5 seconds.
9. After the verification step is done, everything looks good and open global/overlay/etc/hiera/data/common.yaml and change 'cache_control_beta to original value after 10 hours have passed.

...

1. Clone the git repository in your computer (git@github.com:TheIdentitySelector/thiss-ops.git)
2. Open global/overlay/etc/hiera/data/common.yaml and check that the whitelist is right or change it if needed.

   
   

   Warning
   title Whitelisting
   It is important to set the WHITELIST environment variable to the comma-separated list of the current whitelisted domains before deploying. Ask Marina or Leif to verify the list. The list is updated here Seamless Access Configuration Parameters.

   
   

3. Open global/overlay/etc/hiera/data/common.yaml, check the 's-maxage' under 'cache_control_prod. If the current s-max age is 2 days or 172800 seconds, you need to change it to 10 hours, two days before the deployment. If it is one day, you need to change it to 10 hours exactly 1 day before. We need to do it so the old cache gets cleared from non-fastly cache nodes and new files are requested from our backend during the deployment.
4. It is good to see that backends are not overloaded, you can check the HIT ratio (observability > service overview) and origin latency under CDN services from Fastly GUI for the service 'service.seamlessaccess.org'.
5. Keep an eye on the transaction check in pingodm that it is not failing after lowering the s-maxage.
6. Wait as long as the old 's-maxage' and then proceed to the next step. You can even check in the 'developer tools' of your browser (e.g. Chrome, Firefox) that the response headers have the new s-maxage of 10 hours. You can try by using https://demo.seamlessaccess.org/ 
7. Update the ds_version_prod in global/overlay/etc/hiera/data/common.yaml.
   

   
   

   Code Block
   language bash
   ds_version_prod: '2.1.51' cache_control_prod: 'public, max-age=36000, must-revalidate, s-maxage=172800, proxy-revalidate'

   
   

8. Run git add global/overlay/etc/hiera/data/common.yaml and git commit. You should ofcourse have right to commit in the repository. Run git add global/overlay/etc/hiera/data/common.yamlas well if whitelist is changed. You should ofcourse have right to commit in the repository.
9. Run the script thiss-ops/bump-tagafterwards.
10. To verify that the new version is installed, log in to below servers and enter 'run-cosmo -v'. 

    
    

    static-1.aws1.geant.eu.seamlessaccess.org

    static-1.aws2.geant.eu.seamlessaccess.org

    static-1.ntx.sunet.eu.seamlessaccess.org

    static-1.se-east.sunet.eu.seamlessaccess.org (have to run service sunet-thiss_js restart manually)

    static-2.aws1.geant.eu.seamlessaccess.org

    static-2.aws2.geant.eu.seamlessaccess.org

    static-2.ntx.sunet.eu.seamlessaccess.org

11. You can check the status by running the command service docker-thiss_js status.
12. You can also enter 'docker ps' in order to see if the new version is present on docker image tag. 
13. We may have to do more than one version upgrade to make it backward compatible, check https://github.com/TheIdentitySelector/thiss-js/blob/staging/RELEASE.md
14. Check that the login works using demo.seamlessaccess.org. You can check the transaction check & page speed in Pingdom after each upgrade. Page speed shows the response headers and other information for each file loaded from https://service.seamlessaccess.org.
15. It is also good to check the HIT ratio (observability > service overview) and origin latency under CDN services from Fastly GUI for the service 'service.seamlessaccess.org'. Chek that the HIT ratio is high enough, should be around 98 to 99 percent and latency is way below 5 seconds.

17. After the verification step is done, everything looks good and few hours have passed, open global/overlay/etc/hiera/data/common.yaml and change 'max-age' under 'cache_control_prod' to original value.
