Provides some easy helpers on top of the extremely lightweight gliderlabs/alpine:3.1 image to use when downloading, compiling and verifying binaries during your own image build process.

This base image clocks in at 7.549 MB (courtesy of the Alpine image), making it ideal use as a stepping stone for more complicated images.

On build, this image will copy all files from your local bin/docker/blendle/base/ directory, and make them available as executables in your container.

Installs base packages usually required when building binaries from source:

• g++=4.8.3-r0
• gcc=4.8.3-r0
• make=4.1-r0
• file=5.22-r0
• autoconf=2.69-r0
• automake=1.14.1-r0
• coreutils=8.23-r0

Installs base packages used during most download/extract operations:

• curl=7.39.0-r0
• tar=1.28-r0
• gpgme=1.5.1-r0

example:

RUN bnl-apk-install-download-deps \
    && curl -sSL https://github.com/tianon/gosu/releases/download/1.2/gosu-amd64 | \
       tar zxf - -C /usr/local/bin --strip 1 \
    && apk del download-deps

Used to download files and verify the integrity and authenticity of the file using a cryptographic signature.

usage:

bnl-download-and-verify PGP_KEY SIGNATURE_FILE_URL [SOURCE_FILE_URL]

if SOURCE_FILE_URL is omitted, it is assumed to be SIGNATURE_FILE_URL without the final extension.

example:

RUN bnl-download-and-verify BF357DD4 \
      https://github.com/tianon/gosu/releases/download/1.2/gosu-amd64.asc

# curl -sSL -o gosu-amd64 https://github.com/tianon/gosu/releases/download/1.2/gosu-amd64
# curl -sSL -o gosu-amd64.asc https://github.com/tianon/gosu/releases/download/1.2/gosu-amd64.asc
# bnl-pgp-verify BF357DD4 gosu-amd64.asc gosu-amd64

Combines several make steps into a single command.

usage:

bnl-make-install-from-source PATH [OPTIONS]

example:

RUN bnl-make-install-from-source nginx-1.7.10 --with-http_ssl_module

# cd nginx-1.7.10
# ./configure --with-http_ssl_module
# make --jobs=8
# make install
# cd ..
# rm -r nginx-1.7.10

Verifies file based on provided PGP key (see also bnl-download-and-verify).

usage:

bnl-pgp-verify PGP_KEY SIGNATURE_FILE SOURCE_FILE

example:

RUN bnl-pgp-verify BF357DD4 gosu-amd64.asc gosu-amd64

# gpg-agent --daemon
# gpg --verbose --keyserver pgp.mit.edu --recv-keys BF357DD4
# gpg --verbose --verify gosu-amd64.asc gosu-amd64
# pgrep gpg-agent | xargs kill
# rm gosu-amd64.asc
