How to onboard a mirror#

Intended audience

sysadm staff members

A mirror needs credentials to access our journal and to retrieve the contents.

They are manually created by a software Heritage System Administrator. Different credentials must be provided for staging and production.

The URLs to communicate to the mirror operator are defined in Service urls in the ‘Public URLs’ sections, Journal TLS entries and swh-objstorage read-only.

How to create the credentials#

Refer to the credentials creation howto

How to use the credentials#

Refer to the journal client authentication configuration.

How to create the objstorage credentials#

The read-only public storages are protected by an basic authentication mechanism. To allow a mirror to retrieve the content files, they need to have valid credentials.

These credentials are managed and deployed by puppet.

To add a credential in the puppet configuration:

for staging:
- locate the swh::deploy::objstorage::reverse_proxy::basic_auth::users property in the data/deployment/staging/common.yaml file
- add the username in the list
for production
- locate the swh::deploy::objstorage::reverse_proxy::basic_auth::users property in the data/common/common.yaml file
- add the username in the list
Add an entry swh::deploy::objstorage::reverse_proxy::basic_auth::<<username>> in the private/swh-private-data/common.yaml
in the private directory of your puppet sources, execute the following command to refresh the censored credentials (used by octocatalog-diff and vagrant):

private_data/generate-public-data swh-private-data swh-private-data-censored

Deploy the changes to the puppet master
