boot2dockerの環境変数を一発で設定する

More than 5 years have passed since last update.

boot2dockerが新しくなってDOCKER_HOSTだけではなく,DOCKER_CERT_PATHDOCKER_TLS_VERIFYなど設定するべき環境変数が増えた.

boot2dockerはこれらを一発で設定するコマンドを準備している.

$(boot2docker shellinit)

boot2dockerもまだまだ新しくなっているので,環境変数を.zshrc等に直接書くのではなく,このコマンドを書いておくのがよい.以下のように書いている.

.zshrc
if [ "`boot2docker status`" = "running" ]; then
    $(boot2docker shellinit)
fi
