Examples
Override the configured builder instance (--builder)
Same as buildx --builder
.
Specify a build definition file (-f, --file)
Use the -f
/ --file
option to specify the build definition file to use.
The file can be an HCL, JSON or Compose file. If multiple files are specified
they are all read and configurations are combined.
You can pass the names of the targets to build, to build only specific target(s).
The following example builds the db
and webapp-release
targets that are
defined in the docker-bake.dev.hcl
file:
# docker-bake.dev.hcl
group "default" {
targets = ["db", "webapp-dev"]
}
target "webapp-dev" {
dockerfile = "Dockerfile.webapp"
tags = ["docker.io/username/webapp"]
}
target "webapp-release" {
inherits = ["webapp-dev"]
platforms = ["linux/amd64", "linux/arm64"]
}
target "db" {
dockerfile = "Dockerfile.db"
tags = ["docker.io/username/db"]
}
$ docker buildx bake -f docker-bake.dev.hcl db webapp-release
See our file definition guide for more details.
Do not use cache when building the image (--no-cache)
Same as build --no-cache
. Do not use cache when building the image.
Print the options without building (--print)
Prints the resulting options of the targets desired to be built, in a JSON format, without starting a build.
$ docker buildx bake -f docker-bake.hcl --print db
{
"group": {
"default": {
"targets": [
"db"
]
}
},
"target": {
"db": {
"context": "./",
"dockerfile": "Dockerfile",
"tags": [
"docker.io/tiborvass/db"
]
}
}
}
Set type of progress output (--progress)
Same as build --progress
.
Create provenance attestations (--provenance)
Same as build --provenance
.
Always attempt to pull a newer version of the image (--pull)
Same as build --pull
.
Create SBOM attestations (--sbom)
Same as build --sbom
.
Override target configurations from command line (--set)
--set targetpattern.key[.subkey]=value
Override target configurations from command line. The pattern matching syntax is defined in https://golang.org/pkg/path/#Match.
$ docker buildx bake --set target.args.mybuildarg=value
$ docker buildx bake --set target.platform=linux/arm64
$ docker buildx bake --set foo*.args.mybuildarg=value # overrides build arg for all targets starting with 'foo'
$ docker buildx bake --set *.platform=linux/arm64 # overrides platform for all targets
$ docker buildx bake --set foo*.no-cache # bypass caching only for targets starting with 'foo'
