正如您在下面的模板文件中看到的那样,我在“if”和“end”之间声明了几个变量(如 MYSQL_ACCOUNT_PASSWORD 、MYSQL_ACCOUNT_USERNAME 等),我期待编写一个 shell 脚本来获取此类文件中的所有变量。
使用“Golang 的文本/模板包”的 consul 模板格式,恐怕像 cut、sed 或 awk 这样的基本工具无法完成我的工作。我怎样才能做到这一点。
{{- template "findService" "mysql-master-acc" }}
{{- if scratch.Key "mysql-master-acc-service" }}
{{- $mysql_account_db_name := printf "service/%s/mysql-master-acc/%s/config/acc_mysql_db_name" $dc ( scratch.Get "mysql-master-acc-tag" ) | key }}
{{ range scratch.Get "mysql-master-acc-service"}}
MYSQL_ACCOUNT_URL=jdbc:mysql://{{- .Address }}:{{- .Port }}/{{ $mysql_account_db_name }}?useSSL=false&autoReconnect=true&serverTimezone=America/Chicago&rewriteBatchedStatements=true
{{- end }}
{{- if eq (env "SECRETS_BACKEND") "vault" }}
{{ $vault_secret_path := printf "secret/service/%s/kos-mysql-acc/%s" $dc ( scratch.Get "mysql-master-acc-tag" ) -}}
{{ with printf "%s/%s" $vault_secret_path $mysql_account_db_name | secret -}}
MYSQL_ACCOUNT_PASSWORD={{ .Data.password }}
MYSQL_ACCOUNT_USERNAME={{ .Data.username }}
{{- end }}
{{- else if eq ( env "SECRETS_BACKEND" ) "consul" }}
{{- $secretPath := printf "secret/%s/mysql-master-acc/%s/acc_mysql_db_user_password" $dc ( scratch.Get "mysql-master-acc-tag" ) }}
{{- $keyPath := printf "service/%s/mysql-master-acc/%s/config/acc_mysql_db_user" $dc ( scratch.Get "mysql-master-acc-tag" ) }}
MYSQL_ACCOUNT_PASSWORD={{ key $secretPath }}
MYSQL_ACCOUNT_USERNAME={{ key $keyPath }}
{{- end }}
{{- end }}
