27
28## Where can I see it?
29
30Just run `ssh git.charm.sh` for an example. You can also try some of the following commands:
31
32```bash
33# Jump directly to a repo in the TUI
34ssh git.charm.sh -t soft-serve
35
36# Print out a directory tree for a repo
37ssh git.charm.sh soft-serve
38
39# Print a specific file
40ssh git.charm.sh soft-serve/cmd/soft/main.go
41
42# Print a file with syntax highlighting and line numbers
43ssh git.charm.sh soft-serve/cmd/soft/main.go -c -l
44```
45
46## Installation
47
48Soft Serve is a single binary called `soft`. You can get it from a package
49manager:
50
51```bash
52# macOS or Linux
53brew tap charmbracelet/tap && brew install charmbracelet/tap/soft-serve
54
55# Arch Linux
56pacman -S soft-serve
57```
58
59You can also download a binary from the [releases][releases] page. Packages are
60available in Alpine, Debian, and RPM formats. Binaries are available for Linux,
61macOS, and Windows.
62
63[releases]: https://github.com/charmbracelet/soft-serve/releases
64
65Or just install it with `go`:
66
67```bash
68go install github.com/charmbracelet/soft-serve/cmd/soft@latest
69```
70
71## Setting up a server
72
73Make sure `git` is installed, then run `soft`. Thatās it.
74
75A [Docker image][docker] is also available.
76
77[docker]: https://github.com/charmbracelet/soft-serve/blob/main/docker.md
78
79## Configuration
80
81The Soft Serve configuration is simple and straightforward:
82
83```yaml
84# The name of the server to show in the TUI.
85name: Soft Serve
86
87# The host and port to display in the TUI. You may want to change this if your
88# server is accessible from a different host and/or port that what it's
89# actually listening on (for example, if it's behind a reverse proxy).
90host: localhost
91port: 23231
92
93# The access level for anonymous users. Options are: read-write, read-only
94# and no-access.
95anon-access: read-write
96
97# You can grant read-only access to users without private keys.
98allow-keyless: false
99
100# Which repos should appear in the menu?
101repos:
102 - name: Home
103 repo: config
104 private: true
105 note: "Configuration and content repo for this server"
106 - name: Example Public Repo
107 repo: my-public-repo
108 private: false
109 note: "A publicly-accessible repo"
110 - name: Example Private Repo
111 repo: my-private-repo
112 private: true
113 note: "A private repo"
114
115# Authorized users. Admins have full access to all repos. Regular users
116# can read all repos and push to their collab-repos.
117users:
118 - name: Beatrice
119 admin: true
120 public-keys:
121 - ssh-rsa AAAAB3Nz... # redacted
122 - ssh-ed25519 AAAA... # redacted
123 - name: Frankie
124 collab-repos:
125 - my-public-repo
126 - my-private-repo
127 public-keys:
128 - ssh-rsa AAAAB3Nz... # redacted
129 - ssh-ed25519 AAAA... # redacted
130```
131
132When `soft` is run for the first time, it creates a configuration repo
133containing the main README displayed in the TUI as well as a config file for
134user access control.
135
136```
137git clone ssh://localhost:23231/config
138```
139
140The `config` repo is publicly writable by default, so be sure to setup your
141access as desired. You can also set the `SOFT_SERVE_INITIAL_ADMIN_KEY`
142environment variable before first run and it will restrict access to that
143initial public key until you configure things otherwise.
144If you're having trouble, make sure you have generated keys with `ssh-keygen`
145as configuration is not supported for keyless users.
146
147### Server Settings
148
149In addition to the Git-based configuration above, there are a few
150environment-level settings:
151
152* `SOFT_SERVE_PORT`: SSH listen port (_default 23231_)
153* `SOFT_SERVE_HOST`: Address to use in public clone URLs
154* `SOFT_SERVE_BIND_ADDRESS`: Network interface to listen on (_default 0.0.0.0_)
155* `SOFT_SERVE_KEY_PATH`: SSH host key-pair path (_default .ssh/soft_serve_server_ed25519_)
156* `SOFT_SERVE_REPO_PATH`: Path where repos are stored (_default .repos_)
157* `SOFT_SERVE_INITIAL_ADMIN_KEY`: The public key that will initially have admin access to repos (_default ""_). This must be set before `soft` runs for the first time and creates the `config` repo. If set after the `config` repo has been created, this setting has no effect.
158
159## Pushing (and creating!) repos
160
161You can add your Soft Serve server as a remote to any existing repo:
162
163```
164git remote add soft ssh://localhost:23231/REPO
165```
166
167After youāve added the remote just go ahead and push. If the repo doesnāt exist
168on the server itāll be created.
169
170```
171git push soft main
172```
173
174## The Soft Serve TUI
175
176Soft Serve serves a TUI over SSH for browsing repos, viewing files and commits,
177and grabbing clone commands:
178
179```
180ssh localhost -p 23231
181```
182
183It's also possible to ālinkā to a specific repo:
184
185```
186ssh localhost -t -p 23231 REPO
187```
188
189You can use the `tab` key to move between the repo menu and a particular repo.
190When a repo is highlighted you can use the following keys for navigation:
191
192* `R` - View the project's README file
193* `F` - Navigate and view all of the files in the project
194* `C` - View the commit log for the repo
195* `B` - View branches and tags for the repo
196
197## Printing files over SSH
198
199Soft Serve gives you the ability to print out files directly from a repo
200without having to clone or use the TUI.
201
202To print a file tree for the project, just use the repo name as the SSH command
203to your Soft Serve server:
204
205```
206ssh git.charm.sh soft-serve
207```
208
209From there you can print individual files:
210
211```
212ssh git.charm.sh soft-serve/cmd/soft/main.go
213```
214
215You can add the `-c` flag to enable syntax coloring and `-l` to print line
216numbers:
217
218```
219ssh git.charm.sh soft-serve/cmd/soft/main.go -c -l
220```
221
222### A note about RSA keys
223
224Unfortunately, due to a shortcoming in Goās `x/crypto/ssh` package, Soft Serve
225does not currently support access via new SSH RSA keys: only the old SHA-1
226ones will work.
227
228Until we sort this out you'll either need an SHA-1 RSA key or a key with
229another algorithm, e.g. Ed25519. Not sure what type of keys you have?
230You can check with the following:
231
232```
233$ find ~/.ssh/id_*.pub -exec ssh-keygen -l -f {} \;
234```
235
