indy-sdk tutorial

[nekia]

I'll output here about my activity log for the following tutorials. https://github.com/hyperledger/indy-sdk/blob/master/README.md#how-to-tutorials

[nekia]

Write a DID and Query Its Verkey with Rust https://github.com/hyperledger/indy-sdk/blob/master/docs/how-tos/write-did-and-query-verkey/README.md

[nekia]

Issue Link for template.rs is broken https://github.com/hyperledger/indy-sdk/blob/master/docs/how-tos/write-did-and-query-verkey/rust/README.md#step-1

[nekia]

Done installation of libindy

[nekia]

Done build of indy-pool container image

[nekia]

Succeeded to build, but failed to open pool ledger newly

[nekia]

There were 2 reasons why failed to open pool ledger:

• indy-pool is not running I missed starting indy-pool container.

• The default pool_name ( pool ) is bad It seems to be duplicate with some system reserved things. After changing to poolpool, it works without any errors!
