docker-1-环境安装及例子实践
1.安装go
先新建一个Go的工作空间文件夹,文件夹路径建议放在$HOME下:
userdeMacBook-Pro:~ user$ cd $HOME userdeMacBook-Pro:~ user$ mkdir go userdeMacBook-Pro:~ user$ $PATH -bash: ./usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Java/JavaVirtualMachines/jdk-10.0.1.jdk/Contents/Home/bin:/usr/local/bin: No such file or directory
编辑.bash_profile文件，如果没有请新建。在文件末尾加上:
#GOPATH export GOPATH=$HOME/go #GOBIN export GOBIN=$GOPATH/bin export PATH=$PATH:$GOBIN
编辑之后保存，然后执行source命令，使之生效:
userdeMacBook-Pro:~ user$ source .bash_profile userdeMacBook-Pro:~ user$ $PATH -bash: ./usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Java/JavaVirtualMachines/jdk-10.0.1.jdk/Contents/Home/bin:/usr/local/bin:/usr/local/bin:/Users/user/go/bin: No such file or directory
然后进行查看：
userdeMacBook-Pro:~ user$ go env GOARCH="amd64" GOBIN="/Users/user/go/bin" GOCACHE="/Users/user/Library/Caches/go-build" GOEXE="" GOHOSTARCH="amd64" GOHOSTOS="darwin" GOOS="darwin" GOPATH="/Users/user/go" GORACE="" GOROOT="/usr/local/Cellar/go/1.10.1/libexec" GOTMPDIR="" GOTOOLDIR="/usr/local/Cellar/go/1.10.1/libexec/pkg/tool/darwin_amd64" GCCGO="gccgo" CC="clang" CXX="clang++" CGO_ENABLED="1" CGO_CFLAGS="-g -O2" CGO_CPPFLAGS="" CGO_CXXFLAGS="-g -O2" CGO_FFLAGS="-g -O2" CGO_LDFLAGS="-g -O2" PKG_CONFIG="pkg-config" GOGCCFLAGS="-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fdebug-prefix-map=/var/folders/2_/g5wrlg3x75zbzyqvsd5f093r0000gn/T/go-build566845913=/tmp/go-build -gno-record-gcc-switches -fno-common”
2.安装docker
1）下载并安装好Docker.dmg.download，来源：
https://store.docker.com/editions/community/docker-ce-desktop-mac
打开，此时电脑右上角就会出现一个类似鲸鱼的图标：
在运行Hyperledger Fabric时，请确保Docker处于开启状态：
然后就能查看出版本号了：
userdeMBP:~ user$ docker version Client: Version: 18.03.1-ce API version: 1.37 Go version: go1.9.5 Git commit: 9ee9f40 Built: Thu Apr 26 07:13:02 2018 OS/Arch: darwin/amd64 Experimental: false Orchestrator: swarm Server: Engine: Version: 18.03.1-ce API version: 1.37 (minimum version 1.12) Go version: go1.9.5 Git commit: 9ee9f40 Built: Thu Apr 26 07:22:38 2018 OS/Arch: linux/amd64 Experimental: true
userdeMBP:~ user$ docker-compose --version docker-compose version 1.21.1, build 5a3f1a3
2）接下来要进行的一些配置：
Mac电脑配置docker阿里云加速器时，preferences-daemon-register mirrors 中写上加速器地址，写的是别人的，但是也可以自己去申请。
总是提示
"registry-mirrors" : No certs for ic2v8yz.mirror.aliyuncs.com
解决办法：将https改为http，然后在点击Apply&Restart就好了
但是后面发现运行./download-dockerimages.sh -c x86_64-1.0.0 -f x86_64-1.0.0 还是出错了：
userdeMacBook-Pro:e2e_cli user$ ./download-dockerimages.sh -c x86_64-1.0.0 -f x86_64-1.0.0 Pull CA IMAGES Pull FABRIC TAG ===> Pulling fabric Images ==> FABRIC IMAGE: peer Warning: failed to get default registry endpoint from daemon (Error response from daemon: Bad response from Docker engine). Using system default: https://index.docker.io/v1/ Error response from daemon: Bad response from Docker engine
然后后面查，原因是：
从docker1.3.2版本开始默认docker registry使用的是https，当你用docker pull 非https的docker regsitry的时候会报下面错误，所以上面的更改是错误的，不应该改成http
然后我就突然想起，最最开始为https的时候我没有点击apply&Restart，所以下载镜像的时候没能用上阿里云，所以下载timeout。
"registry-mirrors" :这个问题是可以忽略不计的，然后我点击apply&Restart后，再重新运行./download-dockerimages.sh -c x86_64-1.0.0 -f x86_64-1.0.0就成功了
这时候得出来的信息就是之前没下载完的镜像：
userdeMacBook-Pro:e2e_cli user$ ./download-dockerimages.sh -c x86_64-1.0.0 -f x86_64-1.0.0 Pull CA IMAGES Pull FABRIC TAG ===> Pulling fabric Images ==> FABRIC IMAGE: peer x86_64-1.0.0: Pulling from hyperledger/fabric-peer Digest: sha256:b7c1c2a6b356996c3dbe2b9554055cd2b63194cd7a492a83de2dbabf7f7e3c65 Status: Image is up to date for hyperledger/fabric-peer:x86_64-1.0.0 ==> FABRIC IMAGE: orderer x86_64-1.0.0: Pulling from hyperledger/fabric-orderer Digest: sha256:d0ea1f7e7ca04f0c4b7484f8835fd68e9bf13e6fcb700cf3a70f00a4059fc344 Status: Image is up to date for hyperledger/fabric-orderer:x86_64-1.0.0 ==> FABRIC IMAGE: couchdb x86_64-1.0.0: Pulling from hyperledger/fabric-couchdb ........
