python - Aca-py 0.6.0 : INFO Ledger instance not provided error/bug?

Question

我是 Hyperledger Aries 的新手，我无法弄清楚我做错了什么。
环境:

Ubuntu16LTS

Docker 18.09.7 构建 2d0083d

hyperledger-aries-python 版本:0.6.0(源代码)

从 aca-py 存储库( https://github.com/hyperledger/aries-cloudagent-python 我运行:
./scripts/run_docker start -e http://host.docker.internal:8000 -it http 0.0.0.0 8000 -ot http --admin 0.0.0.0 11000 --admin-insecure-mode --log-level DEBUG --genesis-url https://raw.githubusercontent.com/CHempel-esatus/SSI4DE_Genesis/master/pool_transactions_genesis - 痕迹
注意:我尝试了不同的 pool_genesis_transaction 文件并尝试以各种方式传递它们(通过 URL，通过位于 docker conainer 中的文件)。它总是丢弃相同或相似的信息:

2021-03-12 09:48:32,311 aries_cloudagent.config.ledger INFO Ledger instance not provided
2021-03-12 09:48:32,312 aries_cloudagent.core.conductor WARNING No ledger configured

这是完整的输出:

查看演示，我只是不知道为什么我的 aries 无法连接到任何 indy-ledger。
使用具有相同创世文件的 indy-cli 工作正常。 CLI 能够连接，所以我假设所有 pool_genesis_files 都正确。
我做错了什么还是缺少什​​么？

Answer 1

我终于找到了解决方案。我是如何找到它的故事:
短篇小说:
先决条件:在您的机器上安装 indy-sdk、aries-cloudagent、python3_indy 和 python 3.6.9+。如果您不知道该怎么做，请参阅长篇故事。
Python 3.6.9 随 Ubuntu18LTS 开箱即用

在本地安装 aries-cloudagent-python (aca-py)。

首先使用配置命令运行 aca-py 来配置您的 aca-py 实例。使用参数 wallet-type indy

使用 start 命令和您的配置参数正常运行 aca-py。请务必使用 --wallet-type indy 标志才能连接到 indy 分类帐

长篇故事:
在 aries-cloudagent-python (aca-py) 代码中，使用哪个分类帐(例如 indy 分类帐)的配置似乎来自指定的钱包类型。
第一:提供参数:--wallet-type indy
-> 这返回了错误，需要 --wallet-name 和 --wallet-key 参数。所以我提供了他们:

./scripts/run_docker start 
-e http://127.0.0.1:8000 
-it http 127.0.0.1 8000 
-ot http
--admin 127.0.0.1 11000
--admin-insecure-mode
--log-level DEBUG
--genesis-url https://raw.githubusercontent.com/CHempel-esatus/SSI4DE_Genesis/master/pool_transactions_genesis 
--trace 
--recreate-wallet 
--wallet-type indy 
--wallet-name test 
--wallet-key 12345

2nd.:这导致以下错误，告诉没有提供钱包的数据库。

2021-03-16 09:19:45,447 indy.libindy DEBUG _indy_loop_callback: >>> command_handle: 0, err , args: (0,)

2021-03-16 09:19:45,449 indy.libindy DEBUG _indy_loop_callback <<<

    open_wallet.cb)

The above exception was the direct cause of the following exception:

  File "/home/indy/aries_cloudagent/commands/start.py", line 72, in init
    await startup
  File "/home/indy/aries_cloudagent/commands/start.py", line 28, in start_app

    open_wallet.cb)
aries_cloudagent.core.error.ProfileNotFoundError: Wallet 'test' not found: Error: Wallet not found
  Caused by: No wallet database exists

第三:aca-py 的文档在 https://github.com/hyperledger/aries-cloudagent-python/blob/main/DevReadMe.md明确地说:

Running Locally: For local development, we recommend using the provided Docker scripts to run the ACA-Py software

第四:aca-py 可以使用安装在 docker 容器中的 sqlite。要查看 aca-py 是否与 sqlite 兼容，请运行 ./scripts/run_docker start --help它返回可用参数的列表。一种是:

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

第五名:运行

./scripts/run_docker provision 
-e http 
--genesis-url 
https://raw.githubusercontent.com/CHempel-esatus/SSI4DE_Genesis/master/pool_transactions_genesis 
--recreate-wallet 
--wallet-type indy 
--wallet-name test 
--wallet-key 12345

返回

Successfully tagged aries-cloudagent-run:latest
Created new profile
Profile backend: indy
Profile name: test
No public DID
Ledger configured

这很奇怪，因为现在他能够找到sqlite。这似乎正确配置了数据库，因此可以使用它。但是因为它在一个 docker 容器内，并且容器会丢弃每一次更改，所以这个内部配置将永远不可用。
6.为了解决这个问题，我在 Ubuntu18LTS 上安装了来自 https://pypi.org/project/aries-cloudagent/ 的本地云代理包。

pip3 install aries-cloudagent
pip3 install python3_indy

并遵循 indy-sdk https://github.com/hyperledger/indy-sdk 的安装说明
我还在本地机器上安装了 sqlite:

sudo apt install sqlite

7th。:在我重新启动系统后，我执行:

aca-py provision -e http://127.0.0.1:8000 --genesis-url https://raw.githubusercontent.com/CHempel-esatus/SSI4DE_Genesis/master/pool_transactions_genesis --recreate-wallet --wallet-type indy --wallet-name test --wallet-key test

回来

Created new profile
Profile backend: indy
Profile name: test
No public DID
Ledger configured

8th。:在那之后，我云运行 aca-py 并使用 admin-REST-api 连接到我的分类帐
