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
