Successfully Running Containers with NABLA runtime on Ubuntu machines

This is a brief of my detailed tutorial: http://elegance.abdennoor.com/running-containers-nabla-runtime

Prerequisites

OR

  • or in general, having an Ubuntu machine on the cloud or wherever.

Install NABLA and required dependencies

# ###################### Install Dependencies ######################
apt-get -yq update

export GOPATH=$HOME/go
# ###################### Install NABLA Runtime ###################### download runnc source code
go get github.com/nabla-containers/runnc
cd ${GOPATH}/src/github.com/nabla-containers/runnc
# build the binary runnc and other binaries needed
make container-build
# Validate the Build
ls -lh build/{nabla-run,runnc,runnc-cont}
# Install runnc
cd ${GOPATH}/src/github.com/nabla-containers/runnc

systemctl daemon-reload
systemctl restart docker
docker run hello-world

Run a demo: Node Application

# Download the demo (Node App)
go get github.com/abdennour/nabla-demo-apps
# Build the demo
cd ${GOPATH}/src/github.com/abdennour/nabla-demo-apps/node-express
docker build -t node-express-nabla -f Dockerfile.nabla .
# Validate the build
docker images | grep node-express-nabla
# Run the demo
docker run --rm -t -d --runtime=nabla-runtime -p 9090:8080 node-express-nabla # -t -d run in background
  • Validate the demo:
curl -s http://localhost:9090
# Hello Nabla from http://elegance.abdennoor.com !
