This project pretends to centralize and facilitate the process to
install and configure some Linux projects on major different Linux
Distributions.
Why using curl instead of wget? Daniel Stenberg [explains](https://daniel.haxx.se/docs/curl-vs-wget.html)
that curl works like a traditional Unix `cat` command and can do a
single-shot transfer data
Why not using configuration management tools like [Ansible](https://www.ansible.com/),
[Puppet](https://puppet.com) or [Chef](https://www.chef.io/)? These
great tools require an initial installation step for its operation
which results in additional undesired packages in the OS.
## Supported distributions
| Name | Version |
|:-----------|:-----------------:|
| Ubuntu | 16.04/18.04/20.04 |
| CentOS | 7/8 |
| OpenSUSE | Tumbleweed/Leap |
## How to use this script?
The [install.sh](install.sh) bash script has been created to abstract
the differences between different Linux distributions. For example, in
order to install and configure Docker service the following
instruction is needed:
```bash
curl -fsSL http://bit.ly/install_pkg | PKG="docker docker-compose" bash
```

N -- yes --> O[filters unsupported PKG values];
N -- no --> Q;
O --> P[executes INSTALLER_CMD + filtered PKG] --> Q;
end
end
Q((end));
```
`bit.ly/install_pkg` redirects to the install script in this repository and the invocation above is equivalent to:
```bash
curl -fsSL https://raw.githubusercontent.com/electrocucaracha/pkg-mgr_scripts/master/install.sh | PKG="docker docker-compose" bash
```
### Program environment variables
| Name | Description |
|:-------------|:--------------------------------------------------------------------------|
| PKG | Package name(s) to be installed on the requester.(String value) |
| PKG_UPDATE | Update package manager metadata information.(Boolean value) |
| PKG_DEBUG | Enable verbose output during the execution.(Boolean value) |
### Bindep usage
The cURL package installer can be combined with [bindep tool][1] to
perform multiOS installations. The following example demostrates how
to install the [Portable Hardware Locality tools][2] in the current
machine.
```bash
curl -fsSL http://bit.ly/install_pkg | PKG=bindep bash
cat << EOF > bindep.txt
hwloc [node]
hwloc-lstopo [node platform:suse]
EOF
curl -fsSL http://bit.ly/install_pkg | PKG="$(bindep node -b)" bash
lstopo-no-graphics
```
Or use the [wrapper script][3] provided to run in a single command
```bash
curl -fsSL http://bit.ly/install_bin | PKG_BINDEP_PROFILE=node bash
```
### Installing multiple commands
It's also possible to install multiple command-line tools with a single
cURL call. The following example will install docker, kind and kubectl
commands.
```bash
curl -fsSL http://bit.ly/install_pkg | PKG_COMMANDS_LIST="docker,kind,kubectl" bash
```
