echo "===> Downloading platform binaries"

curl https://nexus.hyperledger.org/content/repositories/releases/org/hyperledger/fabric/fabric-binary/${ARCH}-${VERSION}/fabric-binary-${ARCH}-${VERSION}.tar.gz | tar xz

echo "===> Pulling fabric Images"

dockerFabricPull ${FABRIC_TAG}

echo "===> Pulling fabric ca Image"

dockerCaPull ${CA_TAG}

echo

echo "===> List out hyperledger docker images"

docker images | grep hyperledger*
VERSION：将要安装的fabric的版本
ARCH：取得操作系统类型，例如linux-amd64
MARCH:取得操作系统位数

下载相关的脚本，与镜像本身没有关系
curl https://nexus.hyperledger.org/content/repositories/releases/org/hyperledger/fabric/fabric-binary/${ARCH}-${VERSION}/fabric-binary-${ARCH}-${VERSION}.tar.gz | tar xz
调用dockerFabricPull函数下载镜像，镜像包括：
peer orderer couchdb ccenv javaenv kafka tools zookeeper
docker pull hyperledger/fabric-$IMAGES:$FABRIC_TAG

docker tag hyperledger/fabric-$IMAGES:$FABRIC_TAG hyperledger/fabric-$IMAGES

docker pull  镜像名：版本    （pull下载，会从镜像库自动下载镜像到本机）

docker tag   镜像名：版本  镜像名    （tag重命名，如果不给版本号的话，会当作latest版本，后续使用的时候，也不用加版本号了）

调用dockerCaPull函数下载ca镜像。过程同上。

docker images 显示现有的所有镜像
