Automock helps to reduce code tremendously. But it can be tricky to use at times.
Here are some simple code that you can get started with, to show it works. Sometimes those calls can get complicated and you need to know what works. The code sample below, is simple, straight forward and you won't have problem getting it to work
If we were to use key rotation in Azure storage account, then we can do it by setting up our Azure KeyVault and tying it to a storage account. The problem with this approach is that, it will be harder because right now, we're trying to manage key ourselves.
Typically this is an answer to 'how can i apply key rotation to Azure storage account'.
This is a setup for npm, docker images and react app (This doesn't matter i guess)
In this post, we are going to be building a secure pipeline. When we say secure, we mean
a) No PAT token is saved in source code or as a insecure variable. No credential is leak We also separate the pipeline and allow it to evolve independently.
b) No token is written into docker image. User wil not be able to use docker inspect / docker history to obtain PAT token.
In a nutshell, we use Azure Devops and build machine to install npm packages. Then copy all the files, assets and node_modules into docker for next steps to build it.
I know some of you might say, we want a full containerized build. This is a good way too, if you think about it. you don't have to generate user .npmrc file and somehow maintain that in variable group. It just make the steps so much simpler.
Getting maven to build over proxy can be tricky. So here is an example of a proxy setup which might help. But still you need to ensure that your Maven setings.xml proxy configuration (name and password are correct)
Ok where is the general accepted implementation with react-redux. It is a global / subsection state management that maintain data used in your application. For example, lets say you have a Todo list, you might use, the following objects to keep track of it.
- TODO_ID - when user click on ADD_TODO
- TODO_LIST - keep tracks of all your tasks you have created.
These are all trigger based on actions. This is why we have to setup actions. Action when someone click "Add Task". Then it sends a certain message - "ADD_TODO' to be specific to a reducer.
What is a reducer?
Say you have fire up / dispatch / send out a 'ADD_TODO' instruction and you increment current task id with 1. So you can have a unique Id or some way to keep track of it. This is where you pass it to a reducer. You say hey, my ADD_TODO is fired, get me a new TASK_ID.
Reducer is where you are allowed to changes / update state STATE - TODO_ID.
It just seems so clear to me that having "-" dash as a naming convention is bad and causes more problem. Azure container registry won't like it, storage acount won't like it and probably a few others. But you will never know ......... so it can causes more pain than anything else :(
Using Powershell for Azure Devops Linux agent to refer to variables can be hard to get right essentially just use $(build.SourceBranchName) - the build.SourceBranchName is what listed in the documentation.
You can see one example given below :-
- task: PowerShell@2 displayName: 'PowerShell contruct VersionSuffix if not Master' inputs: targetType: 'inline' script: | Write-Host "Setting up version info" $VersionSuffix = 'prerelease' + '.$(build.SourceBranchName).' + $(build.buildid) write-host "##vso[task.setvariable variable=VersionSuffix]$VersionSuffix" Write-Output "##vso[build.updatebuildnumber]$($env:VersionPrefix)-$VersionSuffix" failOnStderr: true condition: and(succeeded(), ne(variables['Build.SourceBranch'], 'refs/heads/master'))
Terraform expression consist of conditional operators like ==, != and functions that you can leverage to work with input values. For example, lets say you want to concatenate two variable together, you can do that using terraform.
There are a whole lot of functions available which are categorized under string, numeric and collection functions.
Lets have a look at where you can use these functions. Functions are typically classified as expresssion and you can use it within a terraform code.
Let's have a look at the example below :-
In this example, i am combining a couple of function together (chaining) and produce a list as the final output. This snippet shows where we can :-
Disecting the code out further, we have substr functions, which attempts to get a subsection of a string except the last character.
telegraf on target server
--output telegraf.tar.gz -k Placing telegraf executable
in a specific folder.
extracting our telegraf.deb, you can move the binary to /usr/local/bin folder
and configuration file to /user/local/etc/telegraf/telegraf.conf
we are in your expand tar directory, /telegraf/usr/bin
cp telegraf /usr/local/bin
we are in your expand tar directory, /telegraf/etc/telegraf
we need to specify what metrics we would like telegraf to send over.Example below shows the key configuration
for DEV environment that we are interested in.
first is target database and server dns. Here we setup our hostname "urls
and database is called "dev_docker_telegraf".
