There are various ways to deploy our Angular application.
One way is to deploy an Angular app via Docker and Nginx.
To do this just implement the following steps:
**1. Create docker folder **
To keep things organized we create a docker folder at project root.
2. Create nginx.conf file
nginx.conf will contain the configuration for our Nginx server.
Place the configuration file inside
Let's assume the app's API server is running at port 3000. Any request having a path of /api/v1/ will be redirected to our API server running at localhost:3000. Since our docker container is running inside its own docker network we will use the IP
172.17.0.1 to access our host machine's port 3000.
For other details see comments in the
**3. Creating Dockerfile **
Now let's create the Dockerfile which will provide the instructions in creating our test-app-nginx container.
Save Dockerfile inside the
To have a working server our Nginx container should be able to serve our app's Angular assets (dist files). The Dockerfile therefore needs to implement a multi-stage build where the 1st stage will build our dist files.
The 2nd stage will then build our Nginx container and copy the Angular assets from the previous stage into it.
# implement a multi-stage build # 1ST STAGE: Node image for building Angular assets (dist files) # name the node image "builder" FROM node:10 AS builder # set working directory WORKDIR /app # copy all files from current dir to working dir in image COPY . . # install node modules and build assets RUN npm i && npm run build # 2ND STAGE: Nginx to serve Angular assets built from previous stage # nginx state for serving content FROM nginx:alpine # Set working directory to nginx asset directory WORKDIR /usr/share/nginx/html # Remove default nginx static assets RUN rm -rf ./* # copy Angular static assets (dist files) from builder image COPY --from=builder /app/dist . # Container run nginx # -g global directives # daemon off ENTRYPOINT ["nginx", "-g", "daemon off;"]
**4. Create a docker-compose-file **
Place the docker-compose file inside
Make sure that the build context is set properly. In the file we set the context to
../ (relative to location of docker-compose file) which refers to the project root.
It is important to set the context as we will experience errors when the Dockerfile is executed. For example, it may not find the files/folders it needs for the multi-stage build (e.g. package.json).
Another important thing to highlight is that we are mounting the
nginx.conf file we created earlier to the Nginx Docker container. This makes it easy for changes in the nginx.conf file to be reflected in our Nginx container.
Last, we expose port 80 (http) and 443(https).
version: "3.5" services: test-project-nginx: image: nginx build: context: ../ dockerfile: ./docker/nginx/Dockerfile volumes: - ./nginx/nginx.conf:/etc/nginx/nginx.conf ports: - "80:80" - "443:443"
5. Run the Docker Nginx Server
$ cd test-app/docker/
$ docker-compose up
After Docker finishes building, your Nginx server will be running.
Go to your domain and enjoy the sight of your website being served by Nginx.
Until next time. Keep learning.
Stay stoked and code. :)
