我正在尝试构建一个基本映像，Circle CI可使用该映像从ECS加载我的所有其他Docker映像。但是，在构建映像时，我无法在本地模拟远程docker环境。如何在CI中告诉它使用远程Docker，而在本地时如何告诉它使用本地Docker？
这是我的Docker文件
# This Docker image is solely for connecting to ECS and grabbing our other images
### Build & Push Command (Locally):
# Ask @tolicodes for what the AWS_ACCESS_KEY and AWS_SECRET_KEY are
# export AWS_ACCESS_KEY=XXX && export AWS_SECRET_KEY=XXX
# docker build --build-arg AWS_ACCESS_KEY=$AWS_ACCESS_KEY --build-arg AWS_SECRET_KEY=$AWS_SECRET_KEY -f docker_files/website-ci-base.Dockerfile -t xxx.dkr.ecr.us-east-1.amazonaws.com/website:website-ci-base . && docker push xxx.dkr.ecr.us-east-1.amazonaws.com/website:website-ci-base
FROM circleci/node:9.11.1-browsers
### ECS LOGIN
# Make sure that environmental variables can be accessed later
# Rename them to variables that AWS config can use
# Note: that we have to do the rename because someone specified the keys
# In the circle config with different names, and I don't want to mess with
# that -@tolicodes
ARG AWS_ACCESS_KEY
ARG AWS_SECRET_KEY
ENV AWS_ACCESS_KEY_ID=$AWS_ACCESS_KEY
ENV AWS_SECRET_ACCESS_KEY=$AWS_SECRET_KEY
# Python is required by AWS CLI
RUN sudo apt-get update
RUN sudo apt-get install -y python-pip python-dev
# Install and log into CLI. Now we can use ECS
RUN sudo pip install awscli
RUN $(aws ecr get-login --no-include-email --region us-east-1)
我得到了错误
