Upgrade

All instructions to upgrade this project from one release to the next will be documented in this file. Upgrades must be run sequentially, meaning you should not skip minor/major releases while upgrading (fix releases can be skipped).

The format is inspired from Keep a Changelog, and this project adheres to Semantic Versioning.

4.2.x to 4.3.0

DJANGO_STATICFILES_STORAGE environment variable is not used anymore. You have to replace it by DJANGO_STORAGES_STATICFILES_BACKEND.

3.27.x to 4.0.x

Before deploying

First you have to install hashicorp/tls provider by running ./bin/terraform init in the src/aws directory.

Then the new terraform plan must be applied:

$ cd src/aws
$ make apply

Once done, a new ssh key pair has been generated. The public key is in the cloudfront management public keys and you have to use the corresponding ssh private key in your marsha installation. You have to retrieve it and replace your actual ssh private key by this one.

$ ./bin/terraform output cloudfront_ssh_private_key

You also have to remove the DJANGO_CLOUDFRONT_ACCESS_KEY_ID environment variable and add the new one DJANGO_CLOUDFRONT_SIGNED_PUBLIC_KEY_ID. It's value can be retrieve in the terraform output:

$ /bin/terraform output cloudfront_publick_key_id

3.0.0 to 3.1.0

After deploying

  • If you run the AWS migration, remove the variable TF_VAR_migrations,

Before deploying

  • An AWS migration should be run. This migration escapes all existing timed text tracks in the source bucket. This migration is called 0001_encode_timed_text_tracks and you should set the environment variable TF_VAR_migrations with the value 0001_encode_timed_text_tracks.
  • Deploy first the AWS stack using terraform.

2.10.x to 3.0.x

Before switching

  • The deprecated route /lti-video/ is removed. You must move all your existing link using this route to the route /lti/videos/{id} where id is the video id.
  • The deprecated settings DJANGO_LRS_URL, DJANGO_LRS_AUTH_TOKEN, DJANGO_LRS_XAPI_VERSION are not used anymore. See migration from 2.6.x to 2.7.x
  • Setting STATICFILES_AWS_ENABLED is not used anymore. Just delete it you have nothing more to do.

2.9.x to 2.10.x

Nothing to do

2.8.x to 2.9.x

Nothing to do

2.6.x to 2.7.x

After switching

  • LRS configuration is not made anymore in the settings. You should remove the environment variables DJANGO_LRS_URL, DJANGO_LRS_AUTH_TOKEN, DJANGO_LRS_XAPI_VERSION and configure your LRS credentials in the admin for each consumer_site you have. These settings will be removed in the next major release.

2.5.x to 2.6.x

Before switching

  • Static files are now hosted on AWS S3 by default and served via CloudFront. In order to make it work, you need to:

    • Create a new environment variable: DJANGO_AWS_S3_REGION_NAME (see doc for information about how to set this variable),

    • Create a new environment variable: DJANGO_CLOUDFRONT_DOMAIN (see doc for information about how to set this variable),

    • Update your AWS stack to create the necessary buckets, CloudFront distribution and bucket policy. To do so, checkout the new release code and run:

      $ cd src/aws
$ make deploy
$ cd -

    If you prefer to continue hosting your static files on the file system, you need to create a new environment variable: DJANGO_STATICFILES_STORAGE and set it to: django.contrib.staticfiles.storage.ManifestStaticFilesStorage. (see doc for information about how to set this variable).

  • collect static files and run database migrations

    $ make collectstatic
$ make migrate

After switching

  • Remove the DJANGO_AWS_DEFAULT_REGION environment variable.
  • Remove the DJANGO_CLOUDFRONT_URL environment variable.
