| - | ==== 04. [30p] Writing a Dockerfile ==== | + | ==== 04. [20p] Bonus: file upload ==== |
| - | == Subtasks == | + | Bonus task: add a upload image input inside the ''account-details'' that uploads a file to the ''public/images/profile'' subfolder (also: create it!): |
| - | - go to the //**node_app**// folder from the {{:ii:labs:s2:03:tasks:lab3.zip|lab archive}}, which contains the source files for a simple NodeJS application | + | * Use ''type="file"'' attribute on the ''<input>''; |
| - | - write a Dockerfile that will be used to create an image by following the steps below: | + | * Use ''multipart/form-data'' encoding type attribute on the ''<form>'' (Google it!); |
| - | - start **//from//** the latest version of the official NodeJS image, **//node:15.11.0-stretch//** | + | * Inside the Flask route function: |
| - | - **//copy//** the file **//package.json//** from the local host to the current directory in the new image (./); this file is intended to specify the dependencies of the NodeJS application (for example, the Express.js framework) | + | * Actually, [[https://flask.palletsprojects.com/en/3.0.x/patterns/fileuploads/|Read The Fine Manual]] for this! |
| - | - **//run//** the command **//npm install//** to install the dependencies in the file from the previous step | + | * Finally, add an ''<img>'' tag to display the profile photo on the user's account page when everything is done! |
| - | - **//copy//** the source file **//server.js//** to the working directory **///usr/src/app/ //** | + | |
| - | - **//expose//** port 8080 | + | |
| - | - set the **//command//** to run the application; you will run the **//node//** binary to execute the **///usr/src/app/server.js//** file | + | |
| - | - use the previously written Dockerfile to create an image called **//mynodeimage//** | + | |
| - | - start a container running image **//mynodeimage//** on port 12345 in detached (daemon) mode | + | |
| - | - verify that your application works correctly by going to [[http://localhost:12345]] (you should see a "Hello World" text) | + | |
