CodeBuild

CodeBuild Local

I want to test my buildspec.yml file wasting a bunch of time/money on actually running CodeBuild.

git clone https://github.com/aws/aws-codebuild-docker-images.git
cd aws-codebuild-docker-images
cd al2/x86_64/standard/3.0
# cd al2/aarch64/standard/2.0/ If you are Matthew S. Wilson
docker build --tag codebuild:001 . 
# wait a literal eternity
DOCKER_ID=$(docker images codebuild:001 --format "{{.ID}}")
cd /your/local/code/directory
path/to/aws-codebuild-docker-images/local-builds/codebuild_build.sh -i $DOCKER_ID -a $(pwd)/artifacts -m -p isengard_example

CDK

Building CDK Constructs with Cloud9

GITHUB_ALIAS=richardhboyd
# Get the latest version of Node
VERSION=$(nvm ls-remote --lts | grep Latest | tail -1 | grep -o "\(v[0-9][0-9]*\.[0-9][0-9]*\.[0-9][0-9]*\)")
nvm install $VERSION
# Just to be safe, let's grab the latest typescript
npm uninstall -g typescript
npm install -g typescript

# Apparently dotnet is needed now too
sh -c "$(curl -fsSL https://dot.net/v1/dotnet-install.sh)"
export PATH=$PATH:/home/ec2-user/.dotnet

git clone git@github.com:$GITHUB_ALIAS/aws-cdk.git
cd aws-cdk/
git remote add upstream https://github.com/aws/aws-cdk.git
# If you've diverged, I usually check out the last common commit
# git checkout [HASH]
git fetch upstream
git merge upstream/master
git checkout -b feature_branch
# Make your changes
docker build -t aws-cdk .

AWS SAM

Update SAM

# sudo localedef -i en_US -f UTF-8 en_US.UTF-8 # Likely not needed
# Need the exports for env filtering due to issue in Brew
# https://github.com/Linuxbrew/brew/issues/568#issuecomment-357527644
# /home/linuxbrew/.linuxbrew/Homebrew/Library/Homebrew/brew.sh: line 15: warning: setlocale: LC_ALL: cannot change locale (C.UTF-8): No such file or directory
# /home/linuxbrew/.linuxbrew/Homebrew/Library/Homebrew/brew.sh: line 15: warning: setlocale: LC_ALL: cannot change locale (C.UTF-8)
export HOMEBREW_NO_ENV_FILTERING=1
CI=1 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
test -d ~/.linuxbrew && eval $(~/.linuxbrew/bin/brew shellenv)
test -d /home/linuxbrew/.linuxbrew && eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)
test -r ~/.bash_profile && echo -e "export HOMEBREW_NO_ENV_FILTERING=1\neval \$($(brew --prefix)/bin/brew shellenv)" >>~/.bash_profile
echo -e "export HOMEBREW_NO_ENV_FILTERING=1\neval \$($(/home/linuxbrew/.linuxbrew/bin/brew --prefix)/bin/brew shellenv)" >>~/.profile
npm uninstall -g aws-sam-local
sudo pip uninstall aws-sam-cli -y
sudo rm -rf $(which sam)
brew tap aws/tap
brew install aws-sam-cli
ln -sf $(which sam) ~/.c9/bin/sam
ls -la ~/.c9/bin/sam

Python

Update Python Version

sudo -u root -s
VERSION=3.7.4
INSTALL_DIR=/usr/local
sudo yum update -y
sudo yum install gcc openssl-devel bzip2-devel libffi-devel -y
wget https://www.python.org/ftp/python/${VERSION}/Python-${VERSION}.tgz
tar xzf Python-${VERSION}.tgz
cd Python-${VERSION}
./configure --prefix=${INSTALL_DIR}
make -j $(nproc)
make install -j $(nproc)
cd ../
### DANGER ZONE, this will break parts of Cloud9
# Remove old symlinks
rm -rf /etc/alternatives/pip
rm -rf /etc/alternatives/python
# make new symlinks
ln -s ${INSTALL_DIR}/bin/pip${VERSION:0:3} /etc/alternatives/pip
ln -s ${INSTALL_DIR}/bin/python${VERSION:0:3} /etc/alternatives/python
### END DANGER ZONE
exit
#TODO add /home/ec2-user/.local/lib/python3.8/site-packages to 'special' PATH

GitHub and SSH

SSH Keys

From my laptop I run

HOME_DIR=~
aws secretsmanager create-secret --name dev/github/richardhboyd --secret-string file://${HOME_DIR}/.ssh/github --region us-west-2 --profile federate

Then I can run this from my Cloud9 Environment to fetch and set the SSH Keys.

HOME_DIR=/home/ec2-user/
git config --global user.name "Richard Boyd"
git config --global user.email rhboyd@amazon.com
# Add your private key
aws secretsmanager get-secret-value --secret-id dev/github/richardhboyd --query "SecretString" --output text --region us-west-2 > ${HOME_DIR}.ssh/github

#restrict the access to the keys
chmod 400 ${HOME_DIR}.ssh/github

echo "IdentityFile ${HOME_DIR}.ssh/github" > ${HOME_DIR}.ssh/config
chmod 400 ${HOME_DIR}.ssh/config

Hugo

Running Hugo on Cloud9

wget https://github.com/gohugoio/hugo/releases/download/v0.62.1/hugo_0.62.1_Linux-64bit.tar.gz
tar -xvzf hugo_0.62.1_Linux-64bit.tar.gz
sudo mv hugo /usr/local/bin/

REGION=$(curl -s http://169.254.169.254/latest/dynamic/instance-identity/document | sed -n 's/.*"region" : "\([a-z0-9-]*\)",/\1/p')
PREVIEW_URL="https://$C9_PID.vfs.cloud9.$REGION.amazonaws.com/"
hugo serve --bind=0.0.0.0 -p 8080 -b $PREVIEW_URL --appendPort=false --disableFastRender

Corretto

Corretto 11/15

sudo -u root -s
JAVA_VERSION=15
curl -L -o /etc/yum.repos.d/corretto.repo https://yum.corretto.aws/corretto.repo
yum install -y java-${JAVA_VERSION}-amazon-corretto-devel
exit

Maven

sudo -u root -s
wget http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo
sed -i s/\$releasever/6/g /etc/yum.repos.d/epel-apache-maven.repo
yum install -y apache-maven
exit
