Some docker info and commands I use a lot.
// First check your ID docker ps // Then use this ID to get to the bash shell docker exec -it [ID] bash
By default Docker prefixes your container and volume names with the directory it's running in. For example I have a couple of projects with the trunk sub directory where I run docker from. If I run Docker from this sub directory, my volume name will be for example "trunk_db". To choose a custom prefix you can set the COMPOSE_PROJECT_NAME inside the .env file, for example:
Convert image to another architecture
First create a new directory and add a Dockerfile with one line in it:
See if we already have a builderx builder:
docker buildx ls
If you see mybuilder in the output, you already have one. If you haven't one yet, do:
docker buildx create --name mybuilder
Now activate this one:
docker buildx use mybuilder
Now go into the new directory with the new Dockerfile.
Yyou can convert an image to for example arm64 (for Mac Silicon):
docker buildx build --platform linux/arm64 -t my-new-image-name --load .
