# bash-aptfile
|
|
|
|
a simple method of defining apt-get dependencies for an application
|
|
|
|
## requirements
|
|
|
|
- apt-get
|
|
- dpkg
|
|
|
|
## installation
|
|
|
|
```shell
|
|
# curl all the things!
|
|
curl -o /usr/local/bin/aptfile https://raw.githubusercontent.com/seatgeek/bash-aptfile/master/bin/aptfile
|
|
chmod +x /usr/local/bin/aptfile
|
|
```
|
|
|
|
You can *also* create a debian package via docker using `make` with the provided `Dockerfile`. The debian package is made via the wonders of `fpm`:
|
|
|
|
```shell
|
|
git clone https://github.com/seatgeek/bash-aptfile.git
|
|
cd bash-aptfile
|
|
make deb
|
|
|
|
# sudo all the things!
|
|
sudo dpkg -i *.deb
|
|
```
|
|
|
|
## usage
|
|
|
|
Create an `aptfile` in the base of your project:
|
|
|
|
```shell
|
|
#!/usr/bin/env aptfile
|
|
# ^ note the above shebang
|
|
|
|
# trigger an apt-get update
|
|
update
|
|
|
|
# install some packages
|
|
package "build-essential"
|
|
package "git-core"
|
|
package "software-properties-common"
|
|
|
|
# install a ppa
|
|
ppa "fkrull/deadsnakes-python2.7"
|
|
|
|
# install a few more packages from that ppa
|
|
package "python2.7"
|
|
package "python-pip"
|
|
package "python-dev"
|
|
|
|
# setup some debian configuration
|
|
debconf_selection "mysql mysql-server/root_password password root"
|
|
debconf_selection "mysql mysql-server/root_password_again password root"
|
|
|
|
# install another package
|
|
package "mysql-server"
|
|
|
|
# install a package from a download url
|
|
package_from_url "google-chrome-stable" "https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb"
|
|
|
|
# you can also execute arbitrary bash
|
|
echo "🚀 ALL GOOD TO GO"
|
|
```
|
|
|
|
Now you can run it:
|
|
|
|
```shell
|
|
# aptfile *does not* use sudo by default!
|
|
sudo aptfile
|
|
|
|
# enable bash tracing
|
|
TRACE=1 sudo -E aptfile
|
|
|
|
# you can also execute a specific aptfile
|
|
sudo aptfile path/to/your/aptfile
|
|
|
|
# or make the file executable and run it directly
|
|
chmod +x path/to/your/aptfile
|
|
sudo ./aptfile
|
|
```
|
|
|
|
And you'll see the following lovely output:
|
|
|
|
```
|
|

|
|
[NEW] package build-essential
|
|
[NEW] package git-core
|
|

|

|

|
|
[OK] set debconf line: mysql mysql-server/root_password_again password root
|
|
[NEW] package mysql-server
|
|
[NEW] package google-chrome-stable
|
|
🚀 ALL GOOD TO GO
|
|
```
|
|
|
|
Note that `aptfile` runs uses `--force-confnew` - it will forcibly use the package's version of a conf file if a conflict is found.
|
|
|
|
## aptfile primitives
|
|
|
|
You can use any of the following primitives when creating your service's aptfile:
|
|
|
|
### update
|
|
|
|
Runs apt-get update:
|
|
|
|
```shell
|
|
update
|
|
```
|
|
|
|
### package
|
|
|
|
Installs a single package:
|
|
|
|
```shell
|
|
package "git-core"
|
|
```
|
|
|
|
### package_from_url
|
|
|
|
Installs a single package from a url:
|
|
|
|
```shell
|
|
package_from_url "google-chrome-stable" "https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb"
|
|
```
|
|
|
|
### packagelist
|
|
|
|
Installs a multiple packages in one apt call:
|
|
|
|
```shell
|
|
packagelist "git-core" "gitsome"
|
|
```
|
|
|
|
### repository
|
|
|
|
Installs an aptitude repository via `add-apt-repository`:
|
|
|
|
```shell
|
|
repository "deb http://us.archive.ubuntu.com/ubuntu/ saucy universe multiverse"
|
|
repository "ppa:mozillateam/firefox-next"
|
|
```
|
|
|
|
### repository_file
|
|
|
|
Installs an aptitude repository in `/etc/apt/sources.list.d`:
|
|
|
|
```shell
|
|
# Add the exact line to /etc/apt/sources.list.d/google-chrome.list
|
|
repository_file "google-chrome" "deb http://dl.google.com/linux/chrome/deb/ stable main"
|
|
# without 'deb', suite (defaults to lsb_release -sc) and components (defaults to 'main') are added
|
|
# All three lines do the same (on xenial)
|
|
repository_file "git-lfs.list" "deb https://packagecloud.io/github/git-lfs/ubuntu/ xenial main"
|
|
repository_file "git-lfs.list" "https://packagecloud.io/github/git-lfs/ubuntu/ main"
|
|
repository_file "git-lfs.list" "https://packagecloud.io/github/git-lfs/ubuntu/"
|
|
```
|
|
|
|
### ppa
|
|
|
|
The preferred method for installing a ppa as it properly handles not re-running `add-apt-repository`:
|
|
|
|
```shell
|
|
ppa "mozillateam/firefox-next"
|
|
```
|
|
|
|
### debconf_selection
|
|
|
|
Allows you to set a debconf selection:
|
|
|
|
```shell
|
|
debconf_selection "mysql mysql-server/root_password password root"
|
|
```
|
|
|
|
## helper functions
|
|
|
|
These helper functions can be used inside your custom aptfile.
|
|
|
|
### log_fail
|
|
|
|
Logs a message to standard error and exits. If this is called, the full output from the dpkg calls will be output as well for further inspection.
|
|
|
|
```shell
|
|
log_fail "Unable to find the proper package version"
|
|
```
|
|
|
|
### log_info
|
|
|
|
Outputs a message to stdout.
|
|
|
|
```shell
|
|
log_info "🚀 ALL GOOD TO GO"
|
|
```
