Build docker image using Compose file
Hai semuanya di materi kali ini kita akan membahas tentang build docker image melalui compose file. Diantaranya yang akan kita bahas yaitu
- Basic build
- Using context
- Using build args
docker-compose buildcommand options
Ok langsung ja kita ke pembahasan yang pertama
Basic build docker image
Configuration options that are applied at build time. build can be specified either as a string containing a path to the build context or, as an object with the path specified under context and optionally Dockerfile and args:
Berikut adalah file Dockerfile
Kita bisa jalankan menggunakan perintah
docker-compose -f docker-compose.yaml up -d --buildMaka berikut hasilnya:
➜ docker docker-compose -f .\09-docker-compose\build\basic\docker-compose.yaml up -d --build

Using build context
Either a path to a directory containing a Dockerfile, or a url to a git repository.
When the value supplied is a relative path, it is interpreted as relative to the location of the Compose file. This directory is also the build context that is sent to the Docker daemon.
Compose builds and tags it with a generated name, and uses that image thereafter.
Jika dijalankan maka hasilnya seperti berikut:
➜ docker docker-compose -f .\09-docker-compose\build\context\docker-compose.yaml up -d --build

Using build args
Add build arguments, which are environment variables accessible only during the build process.
First, specify the arguments in your Dockerfile:
Then specify the arguments under the build key. You can pass a mapping or a list:

➜ docker docker-compose -f .\09-docker-compose\build\args\list.docker-compose.yaml up -d --build

docker-compose build command options
Services are built once and then tagged, by default as project_service. For example, composetest_db. If the Compose file specifies an image name, the image is tagged with that name, substituting any variables beforehand. See variable substitution.
If you change a service’s Dockerfile or the contents of its build directory, run docker-compose build to rebuild it.
➜ docker docker-compose build --help
Build or rebuild services.
Services are built once and then tagged as `project_service`,
e.g. `composetest_db`. If you change a service''s `Dockerfile` or the
contents of its build directory, you can run `docker-compose build` to rebuild it.
Usage: build [options] [--build-arg key=val...] [--] [SERVICE...]
Options:
--build-arg key=val Set build-time variables for services.
--compress Compress the build context using gzip.
--force-rm Always remove intermediate containers.
-m, --memory MEM Set memory limit for the build container.
--no-cache Do not use cache when building the image.
--no-rm Do not remove intermediate containers after a successful build.
--parallel Build images in parallel.
--progress string Set type of progress output (auto, plain, tty).
--pull Always attempt to pull a newer version of the image.
-q, --quiet Don''t print anything to STDOUT
