Web site–Angular- part 40

Creating  Angular app

ng new InfovalutarWebAng

Then customizing to add angular material

ng add @angular/material


ng generate @angular/material:nav banks

Delete everyhing in app component ( without

<div class=”content” role=”main”>




See if it works. If yes, move the router outlet and footer to app-banks.

Now, I want to solve the CD and to run in a container for the people that do not have Angular installed  – or do not want to.

Remember how it was for .NET Core , that I need just an Internet Connection , Docker and VSCode  ? 

Now it does not work – cannot load application because some bug in .NET Core . Why ? I have been going to .NET Core 3.1 and not updated the docker file…


Now it loads – however, saying that the methid has not an implementation. Solving later.

Now going to

to find same for Angular…

After some attempts, I have this files into .devcontainer


// For format details, see or the definition README at
     “name”: “Angular”,
     “dockerFile”: “DockerfileAng”,   
     // Uncomment the next line to have VS Code connect as an existing non-root user in the container.
     // On Linux, by default, the container user’s UID/GID will be updated to match your local user. See
     // for details on adding a non-root user if none exist.
     // “remoteUser”: “vscode”,

    // Uncomment the next line if you will use a ptrace-based debugger like C++, Go, and Rust
     // “runArgs”: [ “–cap-add=SYS_PTRACE”, “–security-opt”, “seccomp=unconfined” ],
     // Use ‘settings’ to set *default* container specific settings.json values on container create.
     // You can edit these settings after create using File > Preferences > Settings > Remote.
     “settings”: {
         // This dev container does include /bin/bash if you prefer to use it instead of ash.
         “”: “/bin/ash”

    // Use ‘appPort’ to create a container with published ports. If the port isn’t working, be sure
     // your server accepts connections from all interfaces ( or ‘*’), not just localhost.
     // “appPort”: [],

    // Uncomment the next line to run commands after the container is created.
     // “postCreateCommand”: “uname -a”,

    // Add the IDs of extensions you want installed when the container is created in the array
     // below. Note that some extensions may not work in Alpine Linux due to glibc dependencies
     // in native code inside the extension. See for details.
     “extensions”: [],
     “postCreateCommand”: “cd InfovalutarWebAng && npm i”,
     “shutdownAction”: “stopContainer”

and DockerFileAng

FROM alpine:3.10

# This Dockerfile adds a non-root user with sudo access. Use the “remoteUser”
# property in devcontainer.json to use it. On Linux, the container user’s GID/UIDs
# will be updated to match your local UID/GID (when using the dockerFile property).
# See for details.

# Install git, bash, dependencies, and add a non-root user
RUN apk add –no-cache git bash libgcc libstdc++ \
     # Create a non-root user to use if preferred – see
     && addgroup -g $USER_GID $USERNAME \
     && adduser -S -s /bin/bash -u $USER_UID -G $USERNAME $USERNAME \
     # [Optional] Add sudo support for the non-root user
     && apk add –no-cache sudo \
     && echo $USERNAME ALL=\(root\) NOPASSWD:ALL > /etc/sudoers.d/$USERNAME\
     && chmod 0440 /etc/sudoers.d/$USERNAME

RUN apk add –update npm
RUN npm install -g @angular/cli

Now I can run in remote container and ng serve from remote container ( do not forget to be in Angular folder and forward port from VSCode !)

Debug Application under VSCode and Docker–part 22

What I wanted is that people that have only a container application ( docker) and  VSCode ( not Visual Studio , nor .NET Core Framework) be able to debug the application and run it. That means, I no longer require to install .NET Core SDK on the local PC

Read a lot

Some important things :

  1. in the devcontainer.json put  “shutdownAction”: “stopContainer”
  2. Delete continuously the vscode image if something wrong

docker container prune -f

docker images “vs*”

docker image rm <id of the prev image>

Now I have all in place ( see commit )

A .devContainer folder with a DockerFile and devcontainer.json ( to construct the docker container)

A .vscode folder with launch.json , devcontainer.json, settings.json  – to run F5 into the container

All I need is to Launch VSCode, press Remote-Container : Open Folder in Container, goto Infovalutar folder that has the .sln. Then press F5 in VS Code  and voila!

Now, anywhere I go, I can launch VSCode and debug the application.

VSCode and Docker

I am super-excited about Docker – because it gives a new meaning about “ it works on my PC”! ( I have a presentation ready – )

However, I want to state something more important: VSCode is now ready to open Docker Containers!

You have to install:


Name: Docker
Id: ms-azuretools.vscode-docker
Description: Adds syntax highlighting, commands, hover tips, and linting for Dockerfile and docker-compose files.
Version: 0.6.4
Publisher: Microsoft
VS Marketplace Link:


Name: Remote – Containers
Id: ms-vscode-remote.remote-containers
Description: Open any folder inside (or mounted into) a container and take advantage of Visual Studio Code’s full feature set.
Version: 0.59.0
Publisher: Microsoft
VS Marketplace Link:

Or this extension:

Name: Remote Development
Id: ms-vscode-remote.vscode-remote-extensionpack
Description: An extension pack that lets you open any folder in a container, on a remote machine, or in WSL and take advantage of VS Code’s full feature set.
Version: 0.15.0
Publisher: Microsoft
VS Marketplace Link:

I have tried with dotnet try the extensions ( for your reference, you can generate the docker image and run the container by using the files from . Then use the externsion to open the dotnet try files under usr folder )

However, the VSCode has now capabilities over SSH, VSL and Docker. It is a wonderfull world, and now we can say : : it works on my Docker!

( My only regret is that VS 2019 has not  those capabilities)
