|
|
|
1. Adjust demo-image.nix accordingly

|
|
|
2. Run:
|
|
|
|
|
|
|
|
|
|
If in impure mode
|
|
|
|
|
```shell
|
2020-06-14 12:15:00 +08:00
|
|
|
nix-build demo-image.nix
|
2020-06-11 16:22:35 +08:00
|
|
|
./result
|
|
|
|
|
```
|
|
|
|
|
Results in a file called c.img
|
|
|
|
|
|
|
|
|
|
If in pure mode
|
|
|
|
|
```shell
|
2020-06-14 12:15:00 +08:00
|
|
|
nix-build demo-image.nix
|
2020-06-11 16:22:35 +08:00
|
|
|
ls -la ./result
|
|
|
|
|
```
|
|
|
|
|
Results in a symlink to the image in the nix store
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
# Impure/pure mode
|
|
|
|
|
Sometimes it can be useful to build the image _outside_ of the Nix sandbox for debugging purposes.
|
|
|
|
|
|
|
|
|
|
For this purpose we have an attribute called `impureMode` which outputs the shell script used by Nix inside the sandbox to build the image.
