Abstruct: Run Pulsar on a remove vscode (code-server), it help us:

  • Know better of pulsar with default Demo. New features play, communications with new clients and more.
  • It’s a share Dev enviroment, help us review code or repeat issues.
  • For example or dev hackathon.

    Run code-server in Azure

    Steps:
  1. pull codercom/code-server:4.1.0
  2. open port 8080 from Azure vm
  3. install plugin Extension Pack for Java and other plugins
  4. install openjdk11 in container, and configure JAVA_HOME
  5. test HelloWorld.java

    Pull and run code-server

    It keeps access locally if you run with -p 127.0.0.1:8080:8080, so port:port is fine.
    1. mkdir -p ~/.config
    2. docker run -it -d --name code-server -p 8080:8080 \
    3. -v "$HOME/.config:/home/coder/.config" \
    4. -v "$PWD:/home/coder/project" \
    5. -u "$(id -u):$(id -g)" \
    6. -e "DOCKER_USER=$USER" \
    7. codercom/code-server:4.1.0

    Open 8080 port from Azure vm
