# Generalizing Makefiles for All Occasions
|
||
|
|
||
|
- Rules are bad,
|
||
|
- standards are good,
|
||
|
- habits are better.
|
||
|
|
||
|
***
|
||
|
|
||
|
# General Standards
|
||
|
|
||
|
- `make help`
|
||
|
- `make check`
|
||
|
- `sudo make install`
|
||
|
|
||
|
**NB:** we separate `make` from `make install` so that the files are not build with the user `root` as the owner.
|
||
|
|
||
|
***
|
||
|
|
||
|
# Service Standards
|
||
|
|
||
|
- `make backup.tgz`
|
||
|
- `make install`
|
||
|
|
||
|
## Service Backups in Two Files
|
||
|
|
||
|
- `configs`: configuration files, all tracked in git.
|
||
|
- `store`: passwords and binary files, not tracked in git.
|
||
|
|
||
|
## New Abilities Unlocked
|
||
|
|
||
|
- Open Access Administration.
|
||
|
- Sharing admin configs with hacker spaces.

## BEHOLD: The Everything Makefile
|
||
|
|
||
|
***
|
||
|
|
||
|
```make
|
||
|
CONFIGS = $(patsubst /%,%,$(shell cat configs))
|
||
|
STORE = $(patsubst /%,%,$(shell cat store))
|
||
|
CP = mkdir -p $(dir $@) && cp -a
|
||
|
IGNORE_FILE = $(shell test -d .git/info && echo .git/info/exclude || echo .gitignore)
|
||
|
GIT_COMMIT = git commit -m"add $@" --no-gpg-sign --no-signoff
|
||
|
SELECTOR != command -v sk || command -v fzy || command -f fzf
|
||
|
.PHONY: all
|
||
|
all: init backup.tgz $(IGNORE_FILE)
|
||
|
backup.tgz: $(CONFIGS) $(STORE)
|
||
|
tar czf $@ $^
|
||
|
$(IGNORE_FILE): store
|
||
|
echo $(STORE) backup.tgz | tr ' ' '\n' > $@
|
||
|
.PHONY: init
|
||
|
init: configs store
|
||
|
configs store:
|
||
|
while con="$$(find /var /etc/ /sys/ -maxdepth 2 -mindepth 1 -type f 2>/dev/null | $(SELECTOR) -p "Select files for $@\nPress Ctrl+d once done")"; do \
|

echo "$$con"; \
|
||

done > $@
|

$(CONFIGS): %: /%

$(CP) $< $@

git add $@

$(GIT_COMMIT)

$(info made git commit for $@)

$(STORE): %: /%

||
|
$(CP) $< $@
|

|
clean:
|

|
$(RM) -r $(CONFIGS) $(STORE) backup.tgz

## Example: Soft Serve Makefile
|
||
|
|
||
|
<br>
|
||
|
The `configs` file:
|
||
|
|
||
|
```
|
||
|
/etc/soft-serve.conf
|
||
|
/var/lib/soft-serve/data/config.yaml
|
||
|
/var/lib/soft-serve/data/file
|
||
|
/etc/nginx/sites-enabled/soft.dmz.rs
|
||
|
/etc/nginx/sites-available/soft.dmz.rs
|
||
|
```
|
||
|
|
||
|
<br>
|
||
|
The `store` file:
|
||
|
|
||
|
```
|
||
|
/var/lib/soft-serve/data/lfs
|
||
|
/var/lib/soft-serve/data/repo
|
||
|
/var/lib/soft-serve/data/soft
|
||
|
/etc/letsencrypt/archive/soft
|
||
|
/etc/letsencrypt/live/soft.dm
|
||
|
/var/lib/soft-serve/data/ssh/
|
||
|
```

|

- Easy: just use a Makefile.
|
||
|
|
||
|
|
||
|
```make
|
||
|
|
||
|
[ ... ]
|
||
|
|
||
|
public/: src/
|
||
|
python build_pages.py
|
||
|
```
