はじめに
CIツールでterraformを実行する時に、tfnotifyを使いたい。
imageはhashicorp/terraformを使ってるので、terraformのイメージにtfnotifyをインストールする方法を確認する。
imageの取得
$docker pull hashicorp/terraform:0.11.11 0.11.11: Pulling from hashicorp/terraform 4fe2ade4980c: Pull complete 9687e2aa6bcc: Pull complete 99ae8338d458: Pull complete Digest: sha256:1641e454fddceb7ec3c4d2dea3ed98a12f8f9bc74490da680cc4901c49d793b0 Status: Downloaded newer image for hashicorp/terraform:0.11.11 $ docker images REPOSITORY TAG IMAGE ID CREATED SIZE hashicorp/terraform 0.11.11 29edcab3b90b 5 months ago 131MB
コンテナ作成＆起動
[]:~$ docker run -it hashicorp/terraform:0.11.11
Usage: terraform [-version] [-help] <command> [args]
The available commands for execution are listed below.
The most common, useful commands are shown first, followed by
less common or more advanced commands. If you're just getting
started with Terraform, stick with the common commands. For the
other commands, please read the help and docs before usage.
Common commands:
apply Builds or changes infrastructure
console Interactive console for Terraform interpolations
destroy Destroy Terraform-managed infrastructure
env Workspace management
fmt Rewrites config files to canonical format
get Download and install modules for the configuration
graph Create a visual graph of Terraform resources
import Import existing infrastructure into Terraform
init Initialize a Terraform working directory
output Read an output from a state file
plan Generate and show an execution plan
providers Prints a tree of the providers used in the configuration
push Upload this Terraform module to Atlas to run
refresh Update local state file against real resources
show Inspect Terraform state or plan
taint Manually mark a resource for recreation
untaint Manually unmark a resource as tainted
validate Validates the Terraform files
version Prints the Terraform version
workspace Workspace management
All other commands:
debug Debug output management (experimental)
force-unlock Manually unlock the terraform state
state Advanced state management
[]:~$
コンテナイメージのENTRYPOINTがterraformなのでterraformコマンドをオプションなしで打った結果が返ってくる
entrypointをbashに上書きして起動してみる
[]:~$ docker run --entrypoint 'bash' -it hashicorp/terraform:0.11.11 docker: Error response from daemon: OCI runtime create failed: container_linux.go:344: starting container process caused "exec: \"bash\": executable file not found in $PATH": unknown.
bashがない！！
alpine linuxのデフォルトのシェルは「ash」だった！
entrypointをashに変更して起動
[]:~$ docker run --entrypoint 'ash' -it hashicorp/terraform:0.11.11 / # / # uname -a Linux 35b5b447d9a4 4.9.125-linuxkit #1 SMP Fri Sep 7 08:20:28 UTC 2018 x86_64 Linux / #

tfnotifyのインストール
goが必要なため、インストールされているか確認
/ # go ash: go: not found
入ってない。
goをインストールする(この後のtfnotifyのビルドの為にlibc-devも合わせてインストール)

実際にCircleCIで実行する場合のconfig.ymlは以下
(追記)terraformのバージョン次第で、goのバージョンが違うので注意
古いとGOPATHを明示的に指定する必要がある。
