Custom catalogs
Add catalogs besides the official one, browse them together, and what changes for apps that come from them.
The manager lists apps from the official Appflare catalog. An admin can add more
catalogs: a company's internal apps, a community collection, or your own. A custom
catalog works like the official one. It publishes an index.json and a signed
release for each app, and the manager installs and updates its apps the same way.
Only prebuilt releases are installed from a catalog you add. An app that a custom catalog lists as built in your account or as self-deploying is left out of the Catalog page, and installing or updating it is refused: "This catalog's index is not signed; only prebuilt releases are installed from added catalogs." A release is signed with the catalog's key, but those entries are trusted by what the index says, and a custom catalog's index is not signed yet. Signing the index is what would allow them later.
The difference is who you trust. Every artifact from a custom catalog must be signed with that catalog's own key, which you paste in when you add it. Appflare's maintainers do not review the apps in a catalog you add, so add only catalogs whose owner you trust.
The catalogs list
Open Settings > Catalogs. The list shows the official catalog, labelled Official, and every catalog you added, each with its label and colour, its index URL, the key ids and fingerprints of its keys, and how many apps are installed from it. Members see the list; only admins change it.
Each catalog has a switch. Turning a catalog off hides its apps from the Catalog page and stops update checks for apps installed from it, until you turn it back on. Nothing is uninstalled. The official catalog can be turned off too, but never removed. It is always verified with the keys built into Appflare.
Add a catalog
Select Add catalog and fill in:
- Index URL: the address of the catalog's
index.json. It must start withhttps://. - Public key: the line the catalog publishes for this, which looks like
{"keyId":"...","publicKeyBase64":"..."}. Paste it exactly. During a key change a catalog may publish a list of up to four such keys in square brackets; paste the whole list. The dialog shows each key's fingerprint back (SHA256:...). Compare it with the fingerprint the catalog's owner published, somewhere you already trust, before you save. A key may not be one of the official catalog's keys, nor reuse one of their key ids. - Label: the name shown on the catalog's apps, such as
Acme internal. - Colour: the colour of that label.
When you select Check and add, the manager fetches the index, checks that it is a valid catalog index, and verifies the signature of one released app's manifest with the key you pasted. Only then is the catalog added. If the index cannot be fetched, is not a catalog index, or the signature does not verify, the catalog is not added and the dialog says why. A manager takes up to five added catalogs.
Browse apps from several catalogs
The Catalog page lists the apps of every catalog that is on, together. Each app's page shows a source badge with the catalog's label and colour. Use the Catalog choice in the search field's filter menu (shown once you have added a catalog) to show one catalog's apps only. Refresh fetches every catalog that is on; the cron does the same every 30 minutes, with one request per catalog that costs nothing when its index has not changed.
Apps from a custom catalog show a monogram instead of an icon, cover or screenshots, and no GitHub stars or install counts. The sponsored slot never shows an item from a custom catalog. Images, popularity and the sponsored slot come only from the official catalog (see Browse the catalog).
Apps installed from a custom catalog
An install remembers the catalog it came from, and its page shows that source under Source. Updates, form revisions and the Install checked badge come from that catalog only.
Signatures stay separate the same way. An app from a custom catalog must verify with that catalog's key; the official keys never verify it. The official catalog's apps must verify with the official keys; a custom catalog's key never verifies them.
Edit or remove a catalog
Open an added catalog's actions menu (⋯, next to its switch) and select Edit to change its Label, Colour, Index URL and Public key. When you change the index URL or the key, the manager runs the same checks as when you added it before it saves the change.
To remove a catalog, open the same menu and select Remove. Removing is refused while any app installed from the catalog is still installed: their updates and checks come from that catalog, and its key verifies them. Uninstall those apps first, or turn the catalog off instead.
Anonymous report
If the anonymous report is on, it counts how many custom catalogs the manager has and how many installs come from them. It never includes their URLs, labels, or the names of their apps.
Run your own catalog
The official catalog's repository doubles as a template: copy it, generate a key, and its workflows sign and publish your apps. See Run your own catalog.
