注意：本文所使用的 fabric 版本为 v1.4.3，与其它版本的网络存在差异。手动启动 first-network 网络系列分为三部分：手动启动 first-network 网络（一）手动启动 first-network 网络（二）手动启动 first-network 网络（三）第一篇单纯使用命令行的形式执行 byfn.sh 脚本中的内容，第二篇和第三篇是对手动启动网络过程所使用的命令和配置文件的解释。 1 启动分布式网络手动生成 fabric 网络所需的配置文件后，接下来需要启动区块链中提供网络服务的各个节点。fabric 采用容器技术，使用 docker-compose 这个工具来实现区块链网络所需的节点容器管理，实现方式只需要编写节点相应的配置文件即可。 1.1 docker-compose-cli.yaml 在 first-network 目录下提供了一个 dokcer-compose 工具所需的配置文件 docker-compose-cli.yaml，我们使用该文件启动网络节点，下面是该文件的内容： version: '2' # 表示用的版本 2 的 YAML 版本 volumes: orderer.example.com: peer0.org1.example.com: peer1.org1.example.com: peer0.org2.example

问题 I am using RUN instruction within a Dockerfile to install a rpm RUN yum -y install samplerpm-2.3 However, I want to pass the value "2.3" as an argument. My RUN instruction should look something like: RUN yum -y install samplerpm-$arg where $arg=2.3 回答1: You are looking for --build-arg and the ARG instruction. These are new as of Docker 1.9. Check out https://docs.docker.com/engine/reference/builder/#arg. This will allow you to add ARG arg to the Dockerfile and then build with docker build -

docker-compose使用中遇到的坑

阅读更多关于 docker-compose使用中遇到的坑

docker-compose能实现多个镜像集成，容器的同时启动，使用十分方便。只需要写一个docker-compose.yml文件即可。但是yml文件对格式十分严格。以下是我遇到的错误： ** 第一个： ** ERROR: yaml.scanner.ScannerError: while scanning for the next token found character ‘\t’ that cannot start any token in “.\docker-compose.yml”, line 3, column 3 原因： yml中最前面用了tab，改成空格就好了。对yaml文件格式要求严格。将原来tab改成空格就好第二个： ERROR: yaml.scanner.ScannerError: mapping values are not allowed here in “.\docker-compose.yml”, line 4, column 17 原因：出现这个错误的是因为yaml格式不正确,谷歌定义的yaml格式太严格了,每个冒号后面都必须带有空格来源： CSDN 作者：雪花不落链接： https://blog.csdn.net/weixin_44780082/article/details/90903219
