本篇内容介绍了“怎么获取一个docker镜像以及创建一个docker网络”的有关知识,在实际案例的操作过程中,不少人都会遇到这样的困境,接下来就让小编带领大家学习一下如何处理这些情况吧!希望大家仔细阅读,能够学有所成!
1.获取docker镜像
以下语句将下载包含已编译软件的Ubuntu镜像。
docker pull eosio/eos
作为快速测试,运行镜像并获取对bash shell的访问权限,请执行以下操作:
docker run --rm -it eosio/eos bash
如果可行,你应该得到如下所示的提示,输入cleos
应返回cleos工具的帮助:
root@a5f9eafaab74:/#cleos
ERROR: RequiredError: Subcommand required
Command Line Interface to EOSIO Client
Usage: cleos [OPTIONS] SUBCOMMAND
Options:
-h,--help Print this help message and exit
-u,--url TEXT=http://localhost:8888/
the http/https URL where nodeos is running
--wallet-url TEXT=http://localhost:8888/
the http/https URL where keosd is running
-v,--verbose output verbose actions on error
Subcommands:
version Retrieve version information
create Create various items, on and off the blockchain
get Retrieve various items and information from the blockchain
set Set or update blockchain state
transfer Transfer EOS from account to account
net Interact with local p2p network connections
wallet Interact with local wallet
sign Sign a transaction
push Push arbitrary transactions to the blockchain
multisig Multisig contract commands
system Send eosio.system contract action to the blockchain.
root@a5f9eafaab74:/#
root@a5f9eafaab74:/#exit
键入exit
退出镜像。
2.创建一个docker网络
创建一个docker网络,允许容器相互通信。
docker network create eosnetwork
3.运行容器
运行服务器软件(在端口7777上):
docker run --name server --network=eosnetwork --rm -p 7777:7777 -i eosio/eos /bin/bash -c "nodeos -e -p eosio --plugin eosio::producer_plugin --plugin eosio::chain_api_plugin --plugin eosio::http_plugin -d /mnt/dev/data --http-server-address=0.0.0.0:7777 --access-control-allow-origin=*"
要运行钱包软件(在端口5555上):
docker run --name wallet --network=eosnetwork --rm -p 5555:5555 -i eosio/eos /bin/bash -c "keosd --http-server-address=0.0.0.0:5555"
让我们打开一个bash shell,以便我们可以测试一些工具。
docker run --name tools --network=eosnetwork --rm -it eosio/eos /bin/bash
4.测试下以便确定它是否全部正常工作
现在让我们确保服务器正在运行:
$ cleos -u http://server:7777 get info
# Expected response

}
$ cleos --wallet-url http://wallet:5555 wallet list keys
