Cross-Compling server using podman

Get Containerfile, init.sh and patches folder from this repo, put into the same directory. Or download archive zip with compressed branch and uncompress it.

Run this command to create podman image

podman build --tag tomenet-server-builder -f Containerfile --build-arg CACHEBUST=$(date +%s)

Compile the server with

podman run --rm -v "PATH-WHERE-TO-SAVE-BUILD-SERVER:/srv/build:z" localhost/tomenet-server-builder

You should change PATH-WHERE-TO-SAVE-BUILD-SERVER with proper path, in mine case it is /home/tokariew/tomenet

Folder must exist before running above command, relative path should be proceed with dot or dots

Instead of podman, docker can be used… but it require root privileges.

Server is build on fedora, it will create archive with all files which are needed to run server.

Server will be based on latest commit in official repo

Patching

On 2021-05-18 I added simple ability to apply custom patches to server. For now I added simple patch which move IDDC to the same location as official server.

To apply patch add name of file at the end of command example command earlier like so:

podman run --rm -v "PATH-WHERE-TO-SAVE-BUILD-SERVER:/srv/build:z" localhost/tomenet-server-builder iddcmove.patch

You can generate your own patch file with git diff like so, if you didn't make commit:

git diff --oneline > patchname.patch

Copy generated patch file to patches folder.

Other options

Running script with -t option before patch names will not compile server if latest commit was more than one week ago.

So command below will compile server only if latest commit was less than one week ago:

podman run --rm -v "PATH-WHERE-TO-SAVE-BUILD-SERVER:/srv/build:z" localhost/tomenet-server-builder -t

For compiling with custom patch the -t switch must be provided first

podman run --rm -v "PATH-WHERE-TO-SAVE-BUILD-SERVER:/srv/build:z" localhost/tomenet-server-builder -t casual.patch

Podman vs Docker difference

• Docker require path for building an image. If you are inside directory with Containerfile:

docker build --tag tomenet-server-builder --build-arg CACHEBUST=$(date +%s) .

• When running container with docker localhost/ before image name is not required

docker run --rm -v "PATH-WHERE-TO-SAVE-BUILD-SERVER:/srv/build:z" tomenet-server-builder

Other files in repo?

• make-tomenet-server - script which is runned by systemd on my nas to compile tomenet, it move archived build to my nextcloud "webdav" using rclone, and then sync tomenet folder to mega and dropbox.

• tomenet-compiler.service this is prehistoric file generated by podman which run above script

• tomenet-compiler.timer - systemd timer to run above unit file weekly on mondays at 12:15. If for some reason my nas was offline during that time, it should run after going online
