Docker Env Vars expanded with secrets content

Variables by Secrets

Sample script that allows you to define as environment variables the name of the docker secret that contains the secret value. It will be in charge of analyze all the environment variables searching for the placeholder to substitute the variable value by the secret.

Usage

You can define the next environment variables:

Devops Best Practices

DevOps started out as "Agile Systems Administration". In 2008, Andrew Shafer did a talk called "Agile Infrastucture" addressing issues around involving more of the company in the same disciplines as programmers.

In 2009, Patrick Debois created "DevOpsDays" conference to help to bring it to light. However, it wouldn't begin to trend until about 2010, when people would begin to describe it as a standalone discipline.

Today, DevOps goes beyond just developers, systems administration and infrastructure, its about [dev, ops, agile, cloud, open source and business](https://blogs.the451group.com/opensource/2010/03/03/devops-mixing-dev-ops-agile-cloud-open-source-and-busi

Insight-api使用的express框架对post请求有Body大小限制，默认为100kb，报错位置为：/bitcore/node_modules/raw-body/index.js, line196
发送的post为json格式，根据调用轨迹express的body-parser模块对json格式的大小限制：/bitcore/node_modules/body-parser/lib/types/json.js, line54
调用body-parser的是bitcore web service，现通过修改web service中的调用参数改为200kb：
bitcore/node_modules/bitcore-node/lib/services/web/index.js, line42
整理了bitcore客户端大致结构：
启动bitcored后，读取bitcore-node.json配置文件，启动其中的各项service。
通过log信息判断，p2p service会根据配置文件去连接一个指定的peer端口，此时如果已启动一个bitcoin node，p2p service就可以连接到这个node。如果配置文件没有指定端口，则会建立一个内置的bcoin node，bcoin是一个通过nodejs实现的bitcoin协议。
Bcoin启动代码位置：/bitcore/node_modules/bitcore-node/lib/services/p2p/bcoin.js, line11

区块链用市场代替网络

1/ Blockchains will replace networks with markets.

2/ Humans are the networked species. The first species to network across genetic boundaries and thus seize the world.

3/ Networks allow us to cooperate when we would otherwise go it alone. And networks allocate the fruits of our cooperation.

4/ Overlapping networks create and organize our society. Physical, digital, and mental roads connecting us all.

5/ Money is a network. Religion is a network. A corporation is a network. Roads are a network. Electricity is a network...

  • People used to pay each other in gold and silver. Difficult to transport. Difficult to divide.
  • Paper money was invented. A claim to gold in a bank vault. Easier to transport and divide.
  • Banks gave out more paper money than they had gold in the vault. They ran “fractional reserves”. A real money maker. But every now and then, banks collapsed because of runs on the bank.
  • Central banking was invented. Central banks would be lenders of last resort. Runs on the bank were thus mitigated by banks guaranteeing each other’s deposits through a central bank. The risk of a bank run was not lowered. Its frequency was diminished and its impact was increased. After all, banks remained basically insolvent in this fractional reserve scheme.
  • Banks would still get in trouble. But now, if one bank got in sufficient trouble, they would all be in trouble at the same time. Governments would have to step in
