Maxim Shulga e6034a69a6 Read the environment with typed parsers and apply the documented defaults
set_defaults() assigned os.getenv() results directly, which overwrote the
argparse defaults with None whenever a variable was unset. A default container
therefore ran "seaf-cli config -k delete_confirm_threshold -v None", and the
same for upload_limit and download_limit: none of the three documented
defaults were ever applied.

SEAFILE_UID and SEAFILE_GID had a second problem. argparse type=int applies
only to command line flags, never to set_defaults, so both stayed strings.
The check in setup_uid compares them against pwd integers, and a string is
never equal to one, so usermod ran on every start.

dsc/config.py reads each variable with its documented default and rejects a
malformed or negative value at startup, naming the variable, instead of
passing it on. An empty variable counts as unset.

Booleans are now rendered as true and false rather than Python's True and
False. The daemon reads disable_verify_certificate with its boolean accessor,
which does not recognise the capitalised form. I could not run the daemon to
confirm the previous value's effect, since the AppImage is x86_64 only.

seaf-cli is no longer given a None value for any option.

# docker-seafile-client
Docker image for [Seafile CLI client](https://help.seafile.com/syncing_client/linux-cli/).
Image on Docker Hub:
[snegov/seafile-client](https://hub.docker.com/r/snegov/seafile-client).
### Docker-compose example:
Also available as a ready-to-use [`compose.example.yaml`](compose.example.yaml).
```yaml
services:
seafile-client:
restart: always
image: snegov/seafile-client:0.0.13
environment:
LIBRARY_ID: "79867cbf-2944-488d-9105-852463ecdf9e:my_library"
SERVER_HOST: seafile.example.com
USERNAME: user
PASSWORD: password
SEAFILE_UID: 1000
SEAFILE_GID: 100
hostname: dsc
volumes:
- /home/johndow/seafile:/dsc/seafile
- sync-data:/dsc/seafile-data
container_name: seafile-client
volumes:
sync-data:
```
### Environment variables:
- `LIBRARY_ID` - library to sync, ID or name. Multiple libraries could be
separated by colon `:`.
- `SERVER_HOST` - hostname of your Seafile server, eg: _seafile.example.com_.
If you're using non-standard port, you can specify it here,
eg: _seafile.example.com:8080_.
- `USERNAME` / `PASSWORD` - credentials to access Seafile server.
- `PASSWORD_FILE` - path to a file holding the password, for Docker Compose
and Swarm secrets. Use either `PASSWORD` or `PASSWORD_FILE`, never both.
- `TOKEN` / `TOKEN_FILE` - an API token to authenticate with instead of a
password. A token takes precedence over a password and can be revoked on the
server. Use either `TOKEN` or `TOKEN_FILE`, never both.
- `SEAFILE_UID` / `SEAFILE_GID` - UID/GID of user inside container. You can
use it to set permissions on synced files. Default values are _1000_ / _1000_.
- `DELETE_CONFIRM_THRESHOLD` - represents the number of files that require
confirmation before being deleted simultaneously. Default value is _500_.
- `DISABLE_VERIFY_CERTIFICATE` - set to _true_ to disable server's certificate
verification. Default value is _false_. Booleans accept _true_/_false_,
_1_/_0_, _yes_/_no_ and _on_/_off_, in any case.
- `UPLOAD_LIMIT` / `DOWNLOAD_LIMIT` - upload/download speed limit in B/s
(bytes per second). Default values are _0_ (unlimited).
Numeric variables must be whole, non-negative numbers. A malformed or negative
value stops the container at startup with a message naming the variable,
rather than being passed on to the Seafile client.
### Using Docker secrets:
Mount the secret and point `PASSWORD_FILE` at it, so the password never enters
the environment:
```yaml
services:
seafile-client:
environment:
PASSWORD_FILE: /run/secrets/seafile_password
secrets:
- seafile_password
secrets:
seafile_password:
file: ./seafile_password.txt
```
A trailing newline in the file is ignored; everything else, including
surrounding spaces, is part of the secret.
The client authenticates `seaf-cli` with an API token rather than the account
password, so the password never appears in a command line. The token does
appear there, and command lines are visible to any process in the container.
This is a limitation of `seaf-cli`, which accepts credentials only as
arguments. A token can at least be revoked on the server.
### Volumes:
- `/dsc/seafile-data` Seafile client data directory (sync status, etc).
- `/dsc/seafile` Seafile libraries content.
### Some notes
`LIBRARY_ID` could be library ID or library name. Library ID is a 36-character
string, which is a part of URI when you open library in webUI. Library name is
a name you gave to library when you created it.
Libraries will be synced in subdirectories of `/dsc/seafile` directory inside
container. You can mount it to host directory to access files.
The subdirectory is named after the library, with whitespace replaced by
underscores. A library is skipped with a warning when its name cannot be a
directory of its own: an empty name, `.`, `..`, or a name containing `/`. Two
libraries whose names would produce the same directory both get their library
ID appended, so they never share one. Everything is created under the
libraries directory (`/dsc/seafile`, or the deprecated `/data` when that
exists); a library name can never place it elsewhere.
The container stops gracefully on `docker stop`: it shuts the Seafile daemon
down and exits with code 0. It exits with a nonzero code and an explanatory
message when the daemon fails to start or stop within its timeout, instead of
waiting forever.
`hostname` parameter is optional, but it's recommended to set it to some unique
value, it will be shown in Seafile webUI as client name (`terminal-dsc` in
given example).
`sync-data` volume is optional too, but it's recommended to use it. Otherwise,
sync status will be lost when container is recreated.
At the moment there is no suitable way to confirm deletion of large number of
files. So, if you're going to delete a lot of files, you should set
`DELETE_CONFIRM_THRESHOLD` to some larger value.
