|
|
|
|
This project contains all sources to build the container image `docker.io/volkerraschek/build-image`. The primary goal
|
|
of the image is only to provide an environment to compile source code for `go` or `rust` and package compiled binaries
|
|
as PKG for Arch Linux or as RPM for RHEL based distributions.
|
|
|
|
## Supported environment variables
|
|
|
|
### gnupg
|
|
|
|
#### GNUPG_KEY
|
|
|
|
Import private gpg key via `GPG_KEY`. The private key must be escaped to import the key inside the container image
|
|
correctly. For example:
|
|
|
|
```bash
|
|
GPG_FPR=YOUR_GPG_FINGERPRINT
|
|
GPG_KEY=$(gpg --armor --export-secret-keys ${GPG_FPR} | cat -e | sed -e 's/\$/\\n/g' -e 's/^[ \t]*//g')
|
|
```
|
|
|
|
### makepkg
|
|
|
|
The `makepkg.conf` configuration is composed from the environment variables with the prefix `MAKEPKG_`. Below are some
|
|
examples:
|
|
|
|
`MAKEPKG_PACKAGER="Hugo McKinnock <hugo.mckinnock@example.local>"`
|
|
`MAKEPKG_GPGKEY="0123456789"`
|
|
`MAKEPKG_PKGEXT=.pkg.tar.zst"`
|
|
|
|
### ssh
|
|
|
|
#### SSH_KEY
|
|
|
|
Import private ssh key via `SSH_KEY`. The private key must be escaped to import the key inside the container image
|
|
correctly. For example:
|
|
|
|
```bash
|
|
SSH_KEY=$(cat -e ${HOME}/.ssh/id_rsa | sed -e 's/\$/\\n/g')
|
|
```
|
|
|
|
## Usage
|
|
|
|
### golang
|
|
|
|
To use this image for building golang applications execute this in your root folder of your go project.
|
|
|
|
```bash
|
|
$ docker run \
|
|
--rm \
|
|
--volume ${PWD}:/workspace \
|
|
volkerraschek/build-image:latest \
|
|
go build
|
|
```
|
|
|
|
### makepkg
|
|
|
|
With the following example will be an package be build for Arch Linux. Execute the commond in the root directory of the
|
|
project, where the `PKGBUILD` file is located.
|
|
|
|
```bash
|
|
$ docker run \
|
|
--env MAKEPKG_PACKAGER="Max Mustermann <max.mustermann@example.com" \
|
|
--rm \
|
|
--volume ${PWD}:/workspace \
|
|
volkerraschek/build-image:latest \
|
|
makepkg
|
|
```
|
|
|
|
### rust
|
|
|
|
If you want to compile instead go rust sourcecode, than you can do it similar to the golang example.
|
|
|
|
```bash
|
|
$ docker run \
|
|
--rm \
|
|
--volume ${PWD}:/workspace \
|
|
volkerraschek/build-image:latest \
|
|
cargo build --release
|
|
```
