EOS初探(1) - Docker方式启动EOS

EOS编译曾花了我几个小时，这里使用Docker Hub的镜像启动的方式, 目前使用最新版本1.0.5

目前官网版本更新太快，很多地方搜索出来的信息都已过时，多看下错误信息自己解决

环境准备

Ubuntu 16.04，官网要求Dock版本：

• Docker Docker 17.05 or higher is required
• docker-compose version >= 1.10.0

实际上docker-compose 1.8也是可以运行的，下面是实际运行版本：

eos@mybc:~$ docker -v
Docker version 18.03.1-ce, build 9ee9f40
eos@mybc:~$ docker-compose -v
docker-compose version 1.8.0, build unknown

docker配置文件

准备docker-compose.yml, 如果你的docker-compose版本>=1.10.0，可以使用推荐的version 3的模式（eos/Docker/docker-compose-eosio1.0.yaml）

version: "2"

services:
  nodeosd:
    container_name: nodeosd
    image: eosio/eos:latest
    command: /opt/eosio/bin/nodeosd.sh --data-dir /opt/eosio/bin/data-dir -e
    hostname: nodeosd
    ports:
      - 8888:8888
      - 9876:9876
    expose:
      - "8888"
    volumes:
      - /opt/eosio/data:/opt/eosio/bin/data-dir

  keosd:
    container_name: keosd
    image: eosio/eos:latest
    command: /opt/eosio/bin/keosd --wallet-dir /opt/eosio/bin/data-dir --http-server-address=127.0.0.1:8900
    hostname: keosd
    links:
      - nodeosd
    volumes:
      - /opt/eosio/data:/opt/eosio/bin/data-dir

启动

拉取最新的镜像（速度慢的去搜索镜像加速）和启动

eos@mybc:~$ docker pull eosio/eos:latest
eos@mybc:~$ docker-compose up -d

查看eos启动日志参考docker logs

启动之后可以查看当前信息(这里经过了格式化)：

eos@mybc:~$ curl http://127.0.0.1:8888/v1/chain/get_info
{
    "server_version":"c9b7a247",
    "chain_id":"cf057bbfb72640471fd910bcb67639c22df9f92470936cddc1ade0e2f2e7dc4f",
    "head_block_num":2229,
    "last_irreversible_block_num":2228,
    "last_irreversible_block_id":"000008b44680a25353aa1d3d70ade57900b7ece713439449d19977d8611bc743",
    "head_block_id":"000008b596592d52d604dbf27961ad7fc125e4f26d0c70ad44c34bbfb3e55c59",
    "head_block_time":"2018-06-19T07:05:14.000",
    "head_block_producer":"eosio",
    "virtual_block_cpu_limit":1854163,
    "virtual_block_net_limit":9738884,
    "block_cpu_limit":199900,
    "block_net_limit":1048576
}
eos@mybc:~$ 

这表明EOS启动成功，可以查看下/opt/eosio/data目录，配置文件/区块数据/状态数据都在这个目录下。如果创建了钱包，钱包文件也会在这个目录下。

eos@JD:/opt/eosio/data$ ls
blocks  config.ini  contracts  state
eos@JD:/opt/eosio/data$ 

==contracts目录是编译好的智能合约脚本，后面发行Token需要用到==

配置EOS的CLI

需要永久保存命令的自己直接把alias配置到profile里去

eos@mybc:~$ alias cleos='docker-compose exec keosd /opt/eosio/bin/cleos -u http://nodeosd:8888 --wallet-url http://localhost:8900'
eos@mybc:~$ cleos get info

  "head_block_num": 2749,
  "last_irreversible_block_num": 2748,
  "last_irreversible_block_id": "00000abc4f89b6d0ae2e14be112478aa16e5aeffa1fdf5a03a3afa72060a7e3f",
  "head_block_id": "00000abdc8aa697eabd2f042bfe4cd3803121a9ce65b64537ae1d573bb0296af",

}
