エージェントのインストールでコケる。

結論は, Amazon Linux 2 AMI に対応していないからっぽい。。。

Stackdriver Monitoring エージェント

 One of the configured repositories failed (Google Cloud Monitoring Agent Repository),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:

     1. Contact the upstream for the repository and get them to fix the problem.

     2. Reconfigure the baseurl/etc. for the repository, to point to a working
        upstream. This is most often useful if you are using a newer
        distribution release than is supported by the repository (and the
        packages for the previous distribution release still work).

     3. Run the command with the repository temporarily disabled
            yum --disablerepo=google-cloud-monitoring ...

     4. Disable the repository permanently, so yum won't use it by default. Yum
        will then just ignore the repository until you permanently enable it
        again or use --enablerepo for temporary usage:

            yum-config-manager --disable google-cloud-monitoring
        or
            subscription-manager repos --disable=google-cloud-monitoring

     5. Configure the failing repository to be skipped, if it is unavailable.
        Note that yum will try to contact the repo. when it runs most commands,
        so will have to try and fail each time (and thus. yum will be be much
        slower). If it is a very temporary problem though, this is often a nice
        compromise:

            yum-config-manager --save --setopt=google-cloud-monitoring.skip_if_unavailable=true

理由を探る。

とにもかくにも, install-monitoring-agent.sh を読む。

先ずは, /etc/os-release を . (source) している。

/etc/os-release
NAME="Amazon Linux"
VERSION="2"
ID="amzn"
ID_LIKE="centos rhel fedora"
VERSION_ID="2"
PRETTY_NAME="Amazon Linux 2"
ANSI_COLOR="0;33"
CPE_NAME="cpe:2.3:o:amazon:amazon_linux:2"
HOME_URL="https://amazonlinux.com/"

変数 ID の文字列で分岐。今回は amzn になる。

install-monitoring-agent.sh
install() {
  case "${ID:-}" in
    amzn)
      echo 'Installing agent for Amazon Linux.'
      install_for_amazon_linux
      ;;

baseurl が https://packages.cloud.google.com/yum/repos/google-cloud-monitoring-amzn-x86_64 となるように YUM リポジトリーのファイルを生成, エージェントをインストールする。

install-monitoring-agent.sh
install_rpm() {
  local REPO_NAME="google-cloud-monitoring-${1}-\$basearch${REPO_SUFFIX+-${REPO_SUFFIX}}"
  cat > /etc/yum.repos.d/google-cloud-monitoring.repo <<EOM
[google-cloud-monitoring]

baseurl=https://${REPO_HOST}/yum/repos/${REPO_NAME}

gpgcheck=1
repo_gpgcheck=1
gpgkey=https://${REPO_HOST}/yum/doc/yum-key.gpg
       https://${REPO_HOST}/yum/doc/rpm-package-key.gpg

  yum -y -q install "${AGENT_NAME}"
  VERSION="$(yum list "${AGENT_NAME}" | tail -n 1 |\
    sed -E 's/.*([0-9]+\.[0-9]+\.[0-9]+-[0-9]+).*/\1/')"
  COLLECTD_LOG="/var/log/messages"
}

https://packages.cloud.google.com/yum/repos/google-cloud-monitoring-amzn-x86_64/repodata/primary.xml の中に RPM ファイル名がある。

Amazon Linux 2 には対応していないようだ。。。
