## Spaces Dev Mode
|
29 |
|
30 |
|
31 |
Whenever your commit some changes to your Space repo, the underlying Docker image gets rebuilt, and then a new virtual machine is provisioned to host the new container.
|
32 |
|
33 |
+
The Dev Mode allows you to update your Space much quicker by overriding the Docker image.
|
34 |
|
35 |
+
The Dev Mode Docker image starts your application as a sub-process, allowing you to restart it without stopping the Space container itself.
|
36 |
It also starts a VS Code server and a SSH server in the background for you to connect to the Space.

### Persisting changes
|
58 |
|
59 |
+
The changes you make when the Dev Mode is enabled are not persisted to the Space repo automatically, and by default they will be discarded when the Dev Mode is disabled or when the Space goes to sleep.
|
60 |
|
61 |
+
If you wish to persist changes made while the Dev Mode is enabled, you need to use `git` from inside the Space container (using VS Code or SSH). For example:
|
62 |
|
63 |
```shell
|
64 |
# Add changes and commit them
|
65 |
git add .
|
66 |
+
git commit -m "Persist changes from Dev Mode"
|
67 |
|
68 |
# Push the commit to persist them in the repo
|
69 |
git push

## Limitations
|
92 |
|
93 |
+
The Dev Mode is currently not available for static Spaces. Docker Spaces also have some additional requirements.
|
94 |
|
95 |
### Docker Spaces
|
96 |
|
97 |
+
Dev Mode is supported for Docker Spaces. However, your Space needs to comply with the following rules for the Dev Mode to work properly.
|
98 |
|
99 |
1. The following packages must be installed:
|
100 |
|
101 |
- `bash` (required to establish SSH connections)
|
102 |
- `curl`, `wget` and `procps` (required by the VS Code server process)
|
103 |
+
- `git` and `git-lfs` to be able to commit and push changes from your Dev Mode environment
|
104 |
|
105 |
+
2. Your application code must be located in the `/app` folder for the Dev Mode daemon to be able to detect changes.
|
106 |
|
107 |
3. The `/app` folder must be owned by the user with uid `1000` to allow you to make changes to the code.
|
108 |
|
|
|
110 |
|
111 |
The Dev Mode works well when the base image is debian-based (eg, ubuntu).
|
112 |
|
113 |
+
More exotic linux distros (eg, alpine) are not tested and the Dev Mode is not guaranteed to work on them.
|
114 |
|
115 |
### Example of a compatible Dockerfile

116 |
|
117 |
+
This is an example of a Dockerfile compatible with Spaces Dev Mode.
