Fabric镜像拉取

脚本说明

脚本改自官方,可以拉取fabric ca/peer/orderer/ccenv/tools等镜像，我注释掉了拉取第三方镜像(zookeeper,kafka,couchdb)的代码。

脚本内容

创建脚本vi docker_pull_fabric_images.sh。然后复制下面的内容到脚本。

执行脚本

# 注意:给脚本添加执行权限
# 执行shell可能报错
# 执行.sh脚本时出现$’\r’: 未找到命令
# 是因为脚本在windows下编辑过，windows下的换行带有‘\r’而uninx或者linux下的换行是‘\n’
# 解决办法-->安装dos2unix:
yum install -y dos2unix
# 然后执行命令转换脚本格式：
dos2unix docker_pull_fabric_images.sh.sh
# 脚本赋权
chmod +x docker_pull_fabric_images.sh.sh
# 执行脚本
./docker_pull_fabric_images.sh.sh 1.4.1
