Title: Lightweight Docker images for Free Pascal Compiler
Post by: Signum Temporis on January 12, 2022, 10:01:51 am

Hi,

I've crated lightweight (Alpine based) Docker images for Free Pascal Compiler.

Docker Hub:	https://hub.docker.com/r/signumtemporis/fpc (https://hub.docker.com/r/signumtemporis/fpc)
Source Repository:	https://gitlab.com/SignumTemporis/docker-fpc (https://gitlab.com/SignumTemporis/docker-fpc)
More info:	README.md (https://gitlab.com/SignumTemporis/docker-fpc/-/blob/master/README.md)

Currently supported image variants:

• By target CPU / OS
  • x86_64-linux
  • x86_64-win64 (cross compile)
• By size
  • full -- images containing all units
  • slim -- images containing basic units only (see README.md (https://gitlab.com/SignumTemporis/docker-fpc/-/blob/master/README.md) for details)

Image sizes:

Target CPU/OS	Size variant	Compressed size
x86_64-linux	slim	~29 MB
x86_64-linux	full	~78 MB
x86_64-win64	slim	~32 MB
x86_64-win64	full	~93 MB

Sample usage:
hello.pas

Code: Pascal  [Select][+][-]

1. begin
2.   writeln('Hello world!');
3. end.

Code: Bash  [Select][+][-]

1. docker run --rm -v $(pwd):/workspace signumtemporis/fpc:slim hello.pas

See README.md (https://gitlab.com/SignumTemporis/docker-fpc/-/blob/master/README.md) for more samples.

Comments are welcome.

Regards

Experimenting now. Nice. Great effort.

I usually include lazbuild (so I can compile Lazarus projects) with Lazarus source too in my docker builds and it goes more than 1 Gb in size :D

I've added simple Bats (https://github.com/bats-core/bats-core)-based tests (https://gitlab.com/SignumTemporis/docker-fpc/-/tree/master/test) so that one can easily verify the images after building them on one's own.

Sample test output:

Code: Text  [Select][+][-]

1.  ✓ [fpc-cross-win64-slim] reports version 3.2.2
2.  ✓ [fpc-cross-win64-slim] builds x86-64 Windows executable
3.  ✓ [fpc-cross-win64-slim] has tag signumtemporis/fpc:cross.x86_64-win64.slim
4.  ✓ [fpc-cross-win64-slim] has tag signumtemporis/fpc:3.2.2-cross.x86_64-win64.slim

As I can see, a couple of days ago Free Pascal lived to see its own official Docker images.  That's great!  At long last!
