docker image cannot be snaped

[Open]

Hi @Sgilk ,

I am new to Docker,

I am trying to follow the video example, but i had trouble snapping the app.

I am using ctrlX works App Build Environments and vscode to established a SSH connection.

I run below command:

1) Git clone https://github.com/S-Gilk/ctrlx-docker-mosquitto-interface

2) sudo apt install docker

Now i will need to configure buildx

How to configure buildx? 

When i tried to run build task, it is not recognised in the build task terminal.

warmest regards,

Hello, 

You have to install docker as a snap. i try to give you some examples. 

[Sgilk]

First install Docker.

(snap install docker)

Then, follow the Docker BuildX install instructions here and you should be able to run the build. Make sure you pass your architecture to the build command. ie. (./scripts/build_all.sh "arm64")

Docker BuildX Install Instructions

I managed to snap the file, however when i installed the snap file into the ctrlX, there are some errors with the ui and interface.

I have Px.exe running on my PC background.

When i install the snap file into the ctrlX, the container engine does not show the MQTT broker 

When i run the command below:

boschrexroth@app-builder-amd64:~/ctrlx-docker-mosquitto-interface$ sudo ./scripts/build_all.sh "arm64"

Hello,

Try this and give me a feedback.

There are a number of errors here that indicate an internet connection problem. You are failing to pull the parent images when building from Dockerfile. I don't know your exact networking details, but make sure you have internet access and your proxy is configured correctly. If you can't (wget google.com), you won't be able to build.

After i installed BuildX, i tried running the command below:

It is not able to find the image. 

Did i missed out something? 

[Sgilk]

Again, this looks like an internet connection issue. There are many possibilities of what could be causing the problem, so I can't provide a specific fix in this case. I'd suggest trying this on a personal PC and home network if you are currently on a company PC and VPN. 

Can you (wget google.com) from a bash terminal in your development environment?

Are you on a VPN or using a proxy?

Thank you @MauroRiboniMX for helping!

I did not run docker as normal user

enter the command line below line by line: Source

 sudo addgroup --system docker
 sudo adduser $USER docker
 newgrp docker
 sudo snap disable docker
 sudo snap enable docker

Also before executing ./build_all.sh enter this command line "sudo chmod 777 -R *” to enable every user has the rights to not only access this folder, but also read, write and execute it's files.
