For this demo I will be using a simple hello-world docker image, and tag it as shreyasssk/signatures:1
This creates a digital signature.
$ docker trust key generate key1
This command creates a .pub key in the directory where the
/// SPDX-License-Identifier: GPL-3.0-or-later | |
pragma solidity ^0.8.0; | |
/// @notice Basic ERC20 implementation. | |
contract Token { | |
string public name; | |
string public symbol; | |
uint8 constant public decimals = 18; | |
uint public totalSupply; | |
mapping(address => uint) public balanceOf; |
This mainly demonstrates my goal of preparing a Raspberry Pi to be provisioned prior to its first boot. To do this I have chosen to use the same cloud-init that is the standard for provisioning servers at Amazon EC2, Microsoft Azure, OpenStack, etc.
I found this to be quite challenging because there is little information available for using cloud-init without a cloud. So, this project also servers as a demonstration for anyone on any version of Linux who may want to install from source, and/or use without a cloud. If you fall into that later group, you probably just want to read the code. It's bash
so everything I do, you could also do at the command line. (Even the for
loop.)
This is how to connect to another host with your docker client, without modifying your local Docker installation or when you don't have a local Docker installation.
First be sure to enable the Docker Remote API on the remote host.
This can easily be done with a container.
For HTTP connection use jarkt/docker-remote-api.
