Description

I am trying to install hyperledger fabric locally by following https://hyperledger.github.io/composer/installing/using-playground-locally.html
but facing the below error

"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"

Describe How to Reproduce

-  I am using Ubuntu 14.04, docker 17.03.0-ce and docker-compose, docker-compose version 1.8.1, build 878cff1
- execute "curl -sSL https://hyperledger.github.io/composer/install-hlfv1.sh | bash"
- ARCH variable is not getting picked up, i tried adding ARCH=x86_64 to environment file. but still facing the error

This is because the tag is invalid, check the images tags according to your target OS architecture, for example: linux 64 tag is x86_64-1.0.4, so an image with this tag can be pulled as, " docker pull hyperledger/fabric-peer:x86_64-1.0.4 " then this issue should disappear. Look for your OS ARCH specific tag in the docker image repos.
