Deploying to Fly.io with SQLite

Deploying a Phoenix app to Fly.io is a breeze...is what everyone kept telling me. In fairness, I imagine the process would have been breezier had I just used postgres, but all the sqlite and litestream talk has been far too intriguing to ignore. "Wait", you say. "It is just a flat file. How much harder can it be?"

It is easy to make something harder than it should be. It is hard to take something complex and make it truly simple. flyctl launch does an amazing job at providing a simple interface to the utterly complex task of generating deployment resources, especially now that we are living in a containerd (erm, firecracker) world.

This gist is for anyone who, like me, thinks they know better than to read all of the documentation and therefore necessari

If you link a program with a compiler driver (clang/gcc) in a standard way (not -nostdlib), the following components are usually on the linker command line.

crt1.o (glibc/musl): -no-pie/-pie/-static-pie
- crt1.o: -no-pie
- Scrt1.o: -pie, -shared
- rcrt1.o: -static-pie
- gcrt1.o:
crti.o (glibc/musl)
crtbegin.o

crtbegin.o: -no-pie

to your supervision tree

Why?

Current version of Ansible (1.7.1) does not merge hashes in the include_vars task even if told so via hash_behaviour = merge in your ansible.cfg. ansible/ansible#9116

This action plugin will merge hashes no matter how you have configured your hash_behaviour.

How to setup:

Save include_vars_merged.py to library/plugins/action/include_vars_merged.py

Save include_vars_merged to library/custom/include_vars_merged
