场景

我在节点的compose文件中进行了数据挂载：

 - ../../data/bank1/peer1:/tmp/hyperledger/bank1/peer1

但是运行是依然报错为var/hyperledger/production的权限问题，并且我也已经对../../data/bank1/peer1目录设置了操作权限

报错日志：

panic: Could not create _lifecycle chaincodes install path: mkdir /var/hyperledger/production: permission denied。

根本原因：

首先，Fabric Peer 默认将 fileSystemPath为 /var/hyperledger/production。这表示即使我进行了挂载，但是启动时节点依然会在producction目录下操作，所以并没有挂载正确。

然后，docker compose文件通常以root身份启动运行。但是如果像我一样在YAML文件里设置了user的字段，类似“user: "${LOCAL_UID:-1000}:${LOCAL_GID:-1000}"”，就会以其他身份进行操作。同时，由于var/hyperledger/production目录只能由root用户操作，再加上前面说的挂载不正确，所以会报错没有权限。
