我想知道是否通过运行安装了Hyperledger Fabric 1.2
curl -sSL https://raw.githubusercontent.com/hyperledger/fabric/master/scripts/bootstrap.sh | bash -s 1.2.0
，然后通过运行
curl -sSL https://raw.githubusercontent.com/hyperledger/fabric/master/scripts/bootstrap.sh | bash -s 1.3.0
然后第二个命令将清除与v1.2对应的docker映像？如果不是，那么在docker-compose.yaml中遇到类似image: hyperledger/fabric-ca之类的代码时，docker如何知道要使用哪个版本的hyperledger/fabric-ca？
答案 0 :(得分：0)
来自：https://hyperledger-fabric.readthedocs.io/en/release-1.3/install.html 该脚本执行以下操作：
If needed, clone the hyperledger/fabric-samples repository
Checkout the appropriate version tag
Install the Hyperledger Fabric platform-specific binaries and config files for the version specified into the /bin and /config directories of fabric-samples
Download the Hyperledger Fabric docker images for the version specified
传递1.2.0将会下载相应的docker映像并将其标记为“最新”。 类似地，传递1.3.0将下载相应的docker映像并将其标记为“最新”。其他图像不会被删除（从我在脚本中看到的）。
现在，当您在docker-compose文件中指定image: hyperledger/fabric-ca时，docker将自动寻找latest标签（首先在本地，然后在注册表中）。
由于已经为所需版本运行了引导脚本，因此即使该映像的较新版本在本地可用，相应的映像也会被标记为最新映像-如果先运行1.3.0，然后再运行1.2.0（ 1.2.0将带有最新标签）
以下是运行docker image ls之后的1.2.0，之后是1.3.0，然后是1.3.0
