wallet-type: only "indy" creates DB and tables; "askar" missing

[darrellodonnell]

using version 0.10.4 we noticed that new Agents are force into in-memory wallets, not postgres.

Leaving out wallet-type: in our config.yml results in an in-memory wallet, not the postgres wallet that we need.

setting wallet-type: indy gives us our storage but then dumps out a deprecation note:

At one point there was a wallet-type: askar option but that has vanished it seems. Only basic (default) and indy are supported as options from what I can see:

--wallet-type <wallet-type>
                        Specifies the type of Indy wallet provider to use. Supported internal storage types are 'basic' (memory) and 'indy'. The default (if not specified)
                        is 'basic'. [env var: ACAPY_WALLET_TYPE]

[darrellodonnell]

is it possible that the wallet-storage-type: basic has been confused with wallet-type: askar somehow?

[dbluhm]

--wallet-type askar will work; the help text is just out of date. I'll submit a quick update for that.

If you've attempted to use the askar wallet type and are seeing errors, feel free to post them here. A common issue I've seen is that the postgres version is older than askar requires so I'd keep an eye out for that.

[darrellodonnell]

@dbluhm i thought that we had tried wallet-type: askar and saw immediate failures but a clean start shows that was incorrect. I have an agent running with Askar now. Many thanks!

We had definitely seen the older postgres issues (I somehow ended up with postgres v10 on one machine???). I think the cause of our issues was re-using the wallet-name value. More here...

For those that are interested, if you create a wallet of type indy and then use the same wallet-name: but flip to wallet-type: askar things fail out immediately:

To add to @darrellodonnell 's comment. Switching from indy to askar requires a migration. Scripts can be found here; https://github.com/hyperledger/aries-acapy-tools
