NerdCTL will not use local image when building - docker

I am trying to build a common base image, that many of my other images will use. But Nerdctl/Containerd doesn't seem to check for the image locally first.
Reproduced with the simple example
# Dockerfile.base
FROM python:3
# Dockerfile.child
From mybase:local

I can't figure out how to get it to NOT look for the image on docker.io. All the recommendations for the docker cli do not seem apply or work.

it actually can't pull image locally first .
the nerdctl build image use the buildkitd tools.it has two types of backends.
you can find the answer from https://github.com/containerd/nerdctl/blob/master/docs/build.md

BuildKit: RUN mount secret not mounted, but no error message?

This is a MWE where I try to expose a file called abc within RUN as a secret:
Dockerfile:
# syntax = docker/dockerfile:1.3
FROM alpine:latest
RUN --mount=type=secret,id=aaa,target=/tmp/aaa ls -l /tmp/aaa
Then I run echo 123 > aaa (that's the file that will be exposed) and docker build (or DOCKER_BUILDKIT=1 docker build if that is not the default), but the secret is not to be found. I will be grateful for some help with this (I am running the latest Docker release 20.10.21):

Rebuilding Docker image taking time

Dockerfile has the following content,

WORKDIR /app
COPY package.json .
COPY . /app
And ran the following build command,
docker build -t app:0.1 .
It took 28.4 seconds and below is the terminal logs,

When I run the same build command again, it is taking 14.6 seconds.
However if I pull the node:16.4.2-alpine3.14 using,
docker pull node:16.4.2-alpine3.14
and then run the build command, then build takes only 0.3 seconds
I think, when we build an image, dependencies also get downloaded and that is why the time taken reduces from 28.4 to 14.6 seconds. But why even 14.6 seconds? It should be as less as 0.3 seconds.
Why is this so? What am I missing?
The following could be the reasons it takes 18.4 seconds:
Docker client takes the entire build context to the docker daemon.The build context is the entire directory the Dockerfile.some files or folders can take up a lot of space e.g node_modules. A remedy to this is to add the file that is not required eg .git, node_module, log files to the .dockerignore file to get Docker to ignore some files.
DNS resolution. Check how long it takes to resolve the docker registry using the dig command.
Enabling the buildkit for your build will help with improving the build time. Setting the DOCKER_BUILDKIT=1 environment variable when invoking the docker build command such as:
DOCKER_BUILDKIT=1 docker build .
please look at this link for more information

Why are ARGS specified in `docker-compose.yml` available in `Dockerfile` for `docker compose run` but not `docker compose build`?

Relatively new to Docker and Compose, but I have read every letter of the Docker Compose documentation, and unsuccessfully bounced around SO for hours, with no resolution to the above question.
I have an (example) directory with the following files:
./Dockerfile:
# syntax=docker/dockerfile:1
ARG CUSTOM_NODE_VERSION
FROM node:$CUSTOM_NODE_VERSION
ARG CUSTOM_NODE_VERSION
ARG HELLO
RUN echo "HELLO: -> $HELLO"
RUN echo "NODE_VERSION -> $NODE_VERSION"
RUN echo "CUSTOM_NODE_VERSION -> $CUSTOM_NODE_VERSION"
./docker-compose.yml:
version: "3.8"
services:
test:
build:
context: .
dockerfile: Dockerfile
args:
CUSTOM_NODE_VERSION: alpine
HELLO: 5
What I want is for docker compose build to use the args specified in the docker-compose.yml file, but it doesn't:

This is all the more baffling to me because, per the Compose docs:
args
Add build arguments, which are environment variables accessible only during the build process.
Any help is much appreciated 🙏🏻
Build args were only recently added to compose-cli. Most likely that change hasn't reached the version of docker compose you're running. You can use docker-compose build (with a -) until this feature reaches your install.

This appears to be an issue with WSL 2 with older base images, not docker or the image itself.
Create %userprofile%\.wslconfig file.
Add the following:
[wsl2]
kernelCommandLine = vsyscall=emulate
Restart WSL. wsl --shutdown
Restart Docker Desktop.
