== Pb

=== docker-compose: error while loading shared libraries: libz.so.1: failed to map segment from shared object

<code ->
# mount -o remount,noexec /tmp
# docker-compose
docker-compose: error while loading shared libraries: libz.so.1: failed to map segment from shared object
</code>


==== Solution

<code bash>
mkdir /plop
chmod 1777 /plop                  
export TMPDIR=/plop                  
docker-compose
</code>

Faire un wrapper

<code bash>
mv /usr/local/bin/docker-compose /usr/local/bin/docker-compose-bin
</code>

''/usr/local/bin/docker-compose''
<code bash>
#! /bin/bash

DIR=$(dirname "$(realpath "$0")")
TMPDIR=/tmp2

if [ ! -d "$TMPDIR" ]
then
        mkdir "$TMPDIR"
        chmod 1777 "$TMPDIR"
fi

export TMPDIR
${DIR}/docker-compose-bin "$@"
