本期“技术视野”，将为你介绍如何通过自动化脚本的方式搭建单节点私有链。

基于Dockerfile创建docker镜像

生成Dockerfile

&& rm -rf /opt/src

ENV PATH="/opt/wicc:${PATH}"

WORKDIR /opt/wicc/

EXPOSE 6968 8920 18920

CMD [“./coind"]

build镜像

$ docker build -t waykicoind .

准备相应的环境

创建文件夹目录

$ sudo mkdir -p /opt/docker-instances/waykicoind-regtest

到新创建目录，创建data conf目录

$ sudo mkdir data conf

修改WaykiChain.conf，确保regtest=1设置成功

创建bin目录，并添加run-waykicoind-regtest.sh

cd /opt/docker-instances/waykicoind-regtest \

&& docker run --name waykicoind-regtest -p18920:18920 -p 1968:6968 \

      -v `pwd`/conf/WaykiChain.conf:/root/.WaykiChain/WaykiChain.conf \

      -v `pwd`/data:/root/.WaykiChain/regnet \

      -v `pwd`/bin:/opt/wicc/bin \

      -d waykicoind

启动容器

sh ./bin/run-waykicoind-regtest.sh

初始化节点

导入矿工节点

注意事项

1.  如果是更新节点，务必备份data目录的wallet.dat，并导出钱包私钥。

2.  节点更新的流程包括以下步骤：

①准备build环境的dockerfile。

FROM phusion/baseimage:0.9.18

MAINTAINER will<[email protected]>

ARG branch='test'

ARG debug='-debug'

# Install prerequisites componets

RUN add-apt-repository ppa:bitcoin/bitcoin -y && apt-get update

ADD prepare_prerequisites.sh /tmp/

RUN apt-get install sudo

RUN sh /tmp/prepare_prerequisites.sh

# Create workdir

RUN mkdir -p /opt/src && cd /opt/src

RUN git config --global user.email "[email protected]"

RUN git config --global user.name "will-lzx"

RUN cd /opt/src &&  git clone -b $branch 'https://github.com/WaykiChain/WaykiChain.git' --recursive

RUN cd /opt/src/WaykiChain/linuxshell && sh ./linux.sh \

&& cd /opt/src/WaykiChain/ && sh ./autogen-coin-man.sh "coin${debug}"

WORKDIR /opt/src/WaykiChain/

CMD bash

②获取最近代码并编译，输出coind文件。

$ docker build -t wick-build .

-  docker run -i --rm -v `pwd`/waykichain/:/tmp/waykichain \

wicc-build \

sh -c " git pull || true && git reset --hard origin/test && sh ./autogen-coin-man.sh coin && make && strip ./src/coind  && mv ./src/coind /tmp/waykichain/“

③编译出coind，即可替换已有节点的coind程序，然后重启容器。

④验证是否正常出区块即可。
