#cloud-config # run commands # default: none # runcmd contains a list of either lists or a string # each item will be executed in order at rc.local like level with # output to the console # - runcmd only runs during the first boot # - if the item is a list, the items will be properly executed as if # passed to execve(3) (with the first arg as the command). # - if the item is a string, it will be simply written to the file and # will be interpreted by 'sh' # # Note, that the list has to be proper yaml, so you have to quote # any characters yaml would eat (':' can be problematic) runcmd: - [ ls, -l, / ] - [ sh, -xc, "echo $(date) ': hello world!'" ] - [ sh, -c, echo "=========hello world=========" ] - ls -l /root # Note: Don't write files to /tmp from cloud-init use /run/somedir instead. # Early boot environments can race systemd-tmpfiles-clean LP: #1707222. - mkdir /run/mydir - [ wget, "http://slashdot.org", -O, /run/mydir/index.html ]
