正在提取ca.org1.example.com（hyperledger / fabric-ca：-1.0.4）…错误：无效的标签格式

Question

i tried hyperledger compose online playground and now want to use it locally. but facing below error after all images are successfully pulled and tries to start.

"WARNING: The ARCH variable is not set. Defaulting to a blank string.
Creating network "composer_default" with the default driver
Pulling ca.org1.example.com (hyperledger/fabric-ca:-1.0.4)...
ERROR: invalid tag format"

I am using Ubuntu 14.04, docker 17.03.0-ce and docker-compose, docker-compose version 1.8.1, build 878cff1

Answer 1

From the docker website on tags :

A tag name must be valid ASCII and may contain lowercase and uppercase letters, digits, underscores, periods and dashes. A tag name may not start with a period or a dash and may contain a maximum of 128 characters.

Edit: However, the problem in your case is likely the previous message that an environment variable is not set. The command you are running is likely trying to pull hyperledger/fabric-ca:${ARCH}-1.0.4 but ARCH is replaced by an empty string.

Answer 2

There is similar kind of issue raised in " https://github.com/IBM/hyperledger-fabric-on-linux-one/issues/15 " and one of the suggested approach is to completely clean the image removing all docker images all install scripts and start again.

However i followed this link ( https://hyperledger.github.io/composer/installing/development-tools ) and now everything is up and running
