Docker – Image/Container build

1. Building an image by pulling

Command:

docker image pull <image_name>

For example, I recently used:

docker image pull nvcr.io/nvidia/pytorch:23.05-py3

---

2. Building an image using Dockerfile

Create “Dockerfile” in your directory, and include the followings in the file:

FROM <existing_image_name>
RUN <commands you want to execute in terminal when the image is built>

There are other commands you can contain.

---

3. Creating a container based on an existing image

docker run --gpus all -it --name <container_name> <image_name>

For example,

docker image pull test_container pytorch/pytorch:latest

---

+ If you want to access to a container via VScode:

1. Right-click on the container
2. Select “Attach Visual Studio Code”
